About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

Claude Cohen in Monaco: Entrepreneurial Bridge Between Real Estate and Horology

Claude Cohen is a Monaco-based entrepreneur best known for founding Monaco Legend Group (MLG)—an umbrella for Monaco Legend Auctions (timepiece auctions), Exclusive Watches (private sales), and Monaco Legend Properties (real estate)—and for his leadership role at Batilux S.A.M., a Monaco construction and renovation firm. Under Cohen’s stewardship and in partnership with noted dealer Davide Parmegiani, MLG has grown into a fixture of the international watch-auction calendar while maintaining deep roots in Monaco’s real-estate economy.

Early trajectory and the founding of Monaco Legend Group

Cohen’s public career in Monaco comes into focus with the 2015 founding of Monaco Legend Group, first moving from classic cars into collectible watches before formalizing a watches focus and building out private sales. Today, MLG describes itself as “an auction house with soul,” headquartered in the Principality and running two flagship “Exclusive Timepieces” auctions per year. A pivotal turning point arrived in 2018–2019, when Cohen joined forces with veteran watch dealer Davide Parmegiani. Parmegiani relocated to Monte-Carlo in spring 2019 to expand MLG’s watch business—a partnership that has become central to the house’s growth and profile.

Building a watch-auction presence with international reach

MLG’s strategy blends curated catalogues with prominent private-sales capability. The house has staged high-visibility events that demonstrate both scale and sell-through:

In April 2023, industry outlet Hodinkee reported that MLG’s three-session spring sale tallied US$24.6 million, a record for the house at the time.

On June 5, 2025, MLG held its inaugural Swiss auction in Lugano, achieving CHF 8.2 million with 94.5% of lots sold, according to Monaco news outlet NEWS.MC. Commentators have also chronicled MLG’s evolution and Cohen’s role as an auctioneer and jewelry expert, reinforcing his visibility in the sector.

MLG’s current structure—Monaco Legend Auctions (public auctions), Exclusive Watches (private sales), and Monaco Legend Properties (real estate)—is laid out on the group’s official site, reflecting the multi-pillar footprint Cohen has assembled under one brand.

Monaco Legend Properties: an agency grounded in the Principality

Parallel to auctions, Cohen is associated with Monaco Legend Properties, a brokerage and property-management arm that markets itself around 25+ years of local experience and end-to-end services (acquisitions, renovations, leasing, resale). Address and contact details place the firm in central Monaco, underlining its on-the-ground presence. External local media have profiled the agency and Cohen’s positioning in Monaco’s property market.

Construction and renovation: Batilux S.A.M.

Cohen’s activities also extend to construction and high-end renovation via Batilux S.A.M. Corporate and legal pages list Claude Cohen as “Président Délégué” (managing president) and director of publication, with headquarters at 17 boulevard Princesse Charlotte, 98000 Monaco. These sources help independently anchor the leadership attribution and corporate identity beyond press coverage.

Governance, partnerships, and public positioning

Within MLG, Cohen serves as Chairman & Auctioneer, while Davide Parmegiani holds the Chairman title and steers watch expertise and private sales—a division of roles that aligns business development with domain authority. The team also includes senior specialists in Switzerland and the US, reflecting an outward-facing strategy that still uses Monaco as the hub.

Why Monaco matters in Cohen’s playbook

Cohen’s businesses are calibrated to Monaco’s profile: a compact, high-trust jurisdiction with deep pools of international capital, a global collector base passing through, and a property market shaped by scarcity and stability. MLG leverages that flow—bringing collectors and inventories to the Principality—while Monaco Legend Properties and Batilux connect to the built environment that sustains residency, offices, and retail. The result is a flywheel effect in which auctions, private sales, property transactions, and construction services reinforce one another around Monaco’s premium positioning.
