The Sea-Dweller reference 116600 marked the return of the 40mm case size for the model, a dimension that had been absent from the Sea-Dweller lineup for some time. This reference reintroduced several classic Sea-Dweller design elements, distinguishing it from its larger contemporary, the Sea-Dweller 4000. It was produced for a relatively short period, making it a notable transitional model within the brand's professional tool watch offerings.

This reference features a stainless steel case measuring 40mm in diameter and 15.3mm in thickness. It is equipped with a unidirectional rotating bezel made of black ceramic with a 60-minute graduation. The watch is powered by the automatic caliber 3135, offering a power reserve of approximately 48 hours. A sapphire crystal protects the black dial, which includes a date complication without the cyclops lens, a characteristic feature of the Sea-Dweller line.

Appealing to collectors who appreciate traditional proportions and the technical capabilities of a professional dive watch, the 116600 is recognized for its blend of heritage design and modern materials. Its limited production run contributes to its appeal among enthusiasts seeking a Sea-Dweller with a more classic case size and specific aesthetic details, such as the matte-like black dial and the absence of the cyclops over the date.

The Rolex Sea-Dweller reference 126600, introduced in 2017, marked a significant update to the Sea-Dweller line, commemorating the model's 50th anniversary. This reference is notable for its increased case size and the reintroduction of the single red line of text on the dial, a nod to early Sea-Dweller models. It bridges the gap between the traditional Sea-Dweller and the larger Deepsea models, offering enhanced presence on the wrist while maintaining the core design language of the professional dive watch series.

This model features a 43 mm Oystersteel case, equipped with a helium escape valve, and is fitted with a unidirectional rotating bezel with a black Cerachrom insert. The watch is powered by the Rolex Caliber 3235, an automatic movement known for its precision and a power reserve of approximately 70 hours. A sapphire crystal protects the black dial, which includes a date complication at 3 o'clock, a departure from previous Sea-Dweller models that lacked the Cyclops lens.

The 126600 appeals to collectors seeking a modern Sea-Dweller with historical design cues. Its larger size and the distinctive red text differentiate it within the contemporary Rolex sports watch lineup. While it maintains the robust engineering expected of the Sea-Dweller, its specific aesthetic details and technical upgrades make it a distinct offering for those interested in the evolution of Rolex's professional dive watches.

The Urwerk UR-1001, known as the "Zeit Device," represents a significant departure from traditional horology, even within Urwerk's innovative catalog. It is not a wristwatch but rather a pocket watch or desk clock, designed as a grand complication that tracks time on multiple scales, from seconds to a millennium. This reference showcases Urwerk's commitment to unconventional time displays and mechanical complexity, serving as a flagship demonstration of their engineering philosophy.

The UR-1001 features a substantial case crafted from titanium and steel, housing a complex manual-winding movement. The time is displayed through a combination of satellite indications, retrograde minutes, and digital jumping hours. Beyond standard time, it incorporates a perpetual calendar, a day/night indicator, and a "running reserve" indicator for the power reserve. Its large dimensions and intricate architecture are protected by a sapphire crystal, allowing for a clear view of the multi-layered dial.

This reference appeals to collectors seeking a unique and highly technical horological object that transcends the conventional wristwatch format. It stands as a testament to Urwerk's ability to push boundaries in mechanical timekeeping, offering a long-term perspective on time with its 100-year and 1000-year indicators. The UR-1001 is a limited production piece, underscoring its exclusivity and appeal to those interested in avant-garde independent watchmaking.

The Calibre de Cartier line itself marked a more robust and masculine design direction for Cartier, moving beyond its traditional dress watch aesthetic while retaining a sense of refined luxury.

This particular reference features a 42mm case crafted from stainless steel, providing a contemporary presence on the wrist.
