             Report of Independent Registered Public Accounting Firm

Plan Administrative Committee
The AMETEK Retirement and Savings Plan

We have audited the accompanying statements of assets available for benefits of
The AMETEK Retirement and Savings Plan as of December 31, 2006 and 2005, and the
related statements of changes in assets available for benefits for the years
then ended. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. We were not engaged to perform an
audit of the Plan's internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Plan's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit also includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the assets available for benefits of the Plan at December
31, 2006 and 2005, and the changes in its assets available for benefits for the
years then ended, in conformity with U.S. generally accepted accounting
principles.

Our audits were performed for the purpose of forming an opinion on the financial
statements taken as a whole. The accompanying supplemental schedule of assets
(held at end of year) as of December 31, 2006, is presented for purposes of
additional analysis and is not a required part of the financial statements but
is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in our audits of the financial statements and, in our
opinion, is fairly stated in all material respects in relation to the financial
statements taken as a whole.

                                DECEMBER 31, 2006

1. DESCRIPTION OF THE PLAN

GENERAL

The following brief description of The AMETEK Retirement and Savings Plan ("the
Plan") provides only summarized information. Participants should refer to the
Plan document for a more complete description of the Plan's provisions.

The Plan is a tax-deferred 401(k) defined contribution savings plan, with a
separate retirement feature described below. The Plan provides eligible
employees of AMETEK, Inc. ("AMETEK", or "the Company"), and certain of its
subsidiaries, an opportunity to invest a portion of their compensation, as
defined by the Plan, in one or a combination of investment programs (see Note
3).

PARTICIPANT ELIGIBILITY

Any employee, who is not specifically an ineligible employee as defined by the
Plan, shall become a participant in the Plan as of the entry date that follows
his or her date of hire by at least thirty--one days and is on or after the date
on which the participant first attains age eighteen.

CONTRIBUTIONS

Each year, participants have an opportunity to invest up to 50% of their annual
compensation, as defined by the Plan, in multiples of one percent, except for
certain highly compensated participants who may be subject to certain regulatory
limitations. Certain groups of participants have an opportunity to invest
catch-up contributions up to 75% of their compensation. Participants may also
contribute amounts representing rollovers from other qualified plans. Also in
connection with business acquisitions by AMETEK, account balances from certain
other plans may be transferred into the Plan, or into a separate 401(k) Plan for
businesses acquired by AMETEK. Subsequent to December 31, 2006 (June 1, 2007),
the net assets of the U.S. participants from the Spectro Analytical Instruments
401(k) Savings Plan in the amount of approximately $3.9 million, were
transferred into the Plan. During 2005, the net assets of the U.S. based Taylor
Hobson 401(k) Savings Plan, in the amount of approximately $1.7 million, were
transferred into the Plan. The Plan provides for Company contributions equal to
33 1/3% of the first 6% of compensation contributed by each participant, to a
maximum annual Company contribution of $1,200 per participant. Matching Company
contributions are credited to participants' accounts at the same time their
contributed compensation is invested. However, the Company may make its matching
contribution payment to the Plan at any time prior to the due date prescribed by
law for filing the Company's federal income tax return for that Plan year.

                                DECEMBER 31, 2006

1. DESCRIPTION OF THE PLAN (CONTINUED)

CONTRIBUTIONS (CONTINUED)

The Plan has a retirement feature for eligible salaried and hourly employees of
AMETEK. The Company makes contributions to the Plan on behalf of such employees
equal to a specified percentage of their compensation earned based upon each
participant's age and years of service, up to predetermined limits. Employee
contributions under the retirement feature of the Plan are not permitted.
Investment programs and transfer and exchange privileges available under the
retirement feature are the same as for the savings feature under the Plan.

Forfeited Company contributions from the retirement feature, which are
insignificant in amount, are used to reduce future employer retirement
contributions or to pay Plan administrative expenses.

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's contributions and
allocations of (a) the Company's contributions and (b) Plan net earnings.
Allocations are based on participant earnings and/or account balances, as
defined. The benefit to which a participant is entitled is the balance in the
participant's vested account.

VESTING

Participants are fully vested at all times in both their contributions to the
Plan and in Company contributions under the savings provisions of the Plan.
Company contributions under the retirement feature of the Plan, through December
31, 2006, become fully vested after five years of service. Effective January 1,
2007, Employer Retirement Feature contributions and earnings contributed on or
after January 1, 2007, will become fully vested after three years of service.

PARTICIPANT LOANS

Participants may borrow a minimum of $1,000 or up to a maximum equal to the
lesser of $50,000 or 50% of their account balance. Participants may have up to
two loans outstanding at any time, although only one loan may be for a primary
residence, the sum of which may not exceed the maximum allowable under the Plan.
Repayment terms of the loans are generally limited to no longer than 60 months
from inception or for a reasonable period of time in excess of 60 months for the
purchase of a principal residence, as fixed by the Plan's Administrative
Committee. The loans are secured by the balance in the participant's account,
and bear interest at rates established by the Plan's administrative committee,
which approximate rates charged by commercial lending institutions for
comparable loans. Interest rates on loans outstanding at December 31, 2006 and
2005 ranged between 5.0% and 10.5%. Principal and interest is paid ratably
through payroll deductions. Participant loans outstanding at December 31, 2006
and 2005, respectively, totaled $5,909,283 and $5,843,612 are included in
investments in the accompanying statements of assets available for benefits.

1. DESCRIPTION OF THE PLAN (CONTINUED)

PAYMENT OF BENEFITS

On termination of service, death, disability or retirement, a participant may
receive a lump-sum amount equal to his or her vested account or elect to receive
payment in installments up to a 15-year period but subject to certain
restrictions based on life expectancy. When a participant attains age 59 1/2
while still an employee, he or she can elect to withdraw a specified portion of
his or her vested account balance without incurring an income tax penalty. Also,
in certain cases of financial hardship, a participant may elect to withdraw up
to a specified portion of his or her vested account balance, regardless of age.

PLAN TERMINATION

The Plan is subject to the provisions of the Employee Retirement Income Security
Act of 1974 ("ERISA"). While the Company has not expressed any intent to
terminate the Plan, it is free to do so at any time subject to the provisions of
ERISA, and applicable labor agreements. In the event of Plan termination, each
participant will receive the value of his or her separate vested account.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF FINANCIAL STATEMENTS AND PRESENTATION FORMAT

The accompanying financial statements have been prepared on the accrual basis of
accounting, if applicable, except for the non-accrual of a liability for amounts
owed to withdrawing participants, which are reflected in plan equity in
accordance with U.S. generally accepted accounting principles (see Note 7).

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to make estimates and
assumptions that affect amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates and
assumptions.

RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are
exposed to various risks such as interest rate, market fluctuation and credit
risks. Due to the level of risk associated with certain investment securities,
it is at least reasonably possible that changes in the values of investment
securities will occur in the near term and that such changes could materially
affect participants' account balances and the amounts reported in the
statements of assets available for benefits.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

INVESTMENT VALUATION AND INCOME RECOGNITION

Investments in shares of registered investment companies are valued at quoted
market prices, which represent the net asset values of shares held by the Plan
at year-end. Money market and short-term investments are carried at the fair
value established by the issuer and/or the trustee. Life Insurance Contracts are
carried at the cash surrender value of such policies at year-end. The
participant loans are valued at their outstanding book values, which
approximates fair value.

The Vanguard Retirement Savings Trust is a common collective trust ("CCT") fund
which invests in fully benefit--responsive investment contracts. The fair value
of the participation units in the CCT is based on quoted redemption values on
the last business day of the plan year. The fair value of the CCT is adjusted to
contract value in accordance with the FSP described in Note 9. Contract value
represents contributions made plus interest accrued at the contract value, less
withdrawals.

Purchases and sales of investments are reflected on trade dates. Realized gains
and losses on sales of investments are based on the average cost of such
investments. Interest income is recorded on the accrual basis. Dividend income
is recorded on the ex-dividend date. Income from other investments is recorded
as earned.

The net appreciation or depreciation of investments represents the sum of the
change in the difference between year-end market value and cost of investments,
and the difference between the proceeds received and the cost of investments
sold during the year.

4. INSURANCE CONTRACTS

Some employee contributions are presently used to maintain previously purchased
life insurance policies underwritten by First Colony Life Insurance Company of
Lynchburg, Virginia. Commissions paid on Insurance Contracts are charged
directly against the participants' insurance accounts. This fund continues to be
closed to new participants.

5. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated September 26, 2003, stating that the Plan is qualified under Section
401(a) of the Internal Revenue Code (the "Code") and, therefore, the related
trust is exempt from taxation. Subsequent to this determination by the Internal
Revenue Service, the Plan was amended and restated. Once qualified, the Plan is
required to operate in conformity with the Code to maintain its qualification.
The Plan Sponsor will take all steps necessary, if any, to maintain the Plan's
qualified status.

6. ADMINISTRATIVE EXPENSES

The expenses of administering the Plan are payable from the trust funds, unless
the Company elects to pay such expenses. From inception of the Plan to the
present, the Company has elected to pay such expenses directly.

9. RECENT ACCOUNTING PRONOUNCEMENTS

In December 2005, the Financial Accounting Standards Board (FASB) issued Staff
Position AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive
Investment Contracts Held by Certain Investment Companies Subject to the AICPA
Investment Company Guide and Defined-Contribution Health and Welfare and Pension
Plans (the FSP). The FSP defines the circumstances in which an investment
contract is considered fully benefit responsive and provides certain reporting
and disclosure requirements for fully benefit responsive investment contracts in
defined contribution health and welfare and pension plans. The financial
statement presentation and disclosure provisions of the FSP are effective for
financial statements issued for annual periods ending after December 15, 2006
and are required to be applied retroactively to all prior periods presented for
comparative purposes. The Plan has adopted the provisions of the FSP at December
31, 2006.

As required by the FSP, investments in the accompanying Statements of Assets
Available for Benefits include fully benefit responsive investment contracts
recognized at fair value. AICPA Statement of Position 94-4-1, Reporting of
Investment Contracts Held by Health and Welfare Benefit Plans and Defined
Contribution Pension Plans, as amended, requires fully benefit responsive
investment contracts to be reported at fair value in the Plan's Statement of
Assets Available for Benefits with a corresponding adjustment to reflect these
investments at contract value. The requirements of the FSP have been applied
retroactively to the Statement of Assets Available for Benefits as of December
31, 2005 presented for comparative purposes. Adoption of the FSP had no effect
on the Statement of Changes in Assets Available for Benefits for any period
presented.
