Introducing five new diver's watches that highlight the uniqueness of each company!
Diving watches are a prime example of sports watches, boasting high water resistance and legibility. Originally, they were specialized timepieces for professionals such as divers and military divers, but with the rise of marine sports and casual fashion, they have become popular among the general public. Today, with the trend toward casual business attire, they are popular both on and off the job.
We will introduce five masterpieces from among the diver's watches released in 2025. In addition to their excellent durability that can withstand bad weather and leisure activities, the collection is packed with models that highlight the unique characteristics of each manufacturer.
Tudor Pelagos Ultra Ref. M2543CLA7NU-0001

When it comes to Tudor diver's watches, the vintage-inspired Black Bay is often the first to come to mind, but the modern, high-spec Pelagos also boasts many masterpieces. The Pelagos Ultra was added to the lineup in 2025. Its distinctive feature is its incredible water resistance of 1000m. Despite its exceptional water resistance, the case is relatively compact, measuring just 43mm in diameter and 14.5mm thick. The titanium case is not only lightweight, but also highly resistant to corrosion, even in saltwater.
The dial features a matte black base with white indexes and hands, ensuring excellent visibility with high contrast. The luminous paint comes in two colors, blue and green, ensuring visibility and legibility even in deep water.

Ulysse Nardin "Diver Air" Ref. 3743-170-2A/0A

The Ulysse Nardin Diver Air was announced as the world's lightest mechanical diver's watch. Its incredible lightness, weighing just 52g with the strap attached and 46g without, was achieved through an approach that focused on both the exterior and the movement.
The case measures 44mm in diameter, giving it the impressive size you'd expect from a diver's watch. The caseband is made of titanium, the side parts are made of a composite of Nylo®, made from recycled fishing nets, and carbon fiber, and the bezel is made of carbon fiber. All of these materials are lightweight and boast excellent strength, contributing to the watch's robustness and light weight.
The movement, which can be viewed from both the dial and the case back, has been stripped down to its bare minimum. The baseplate and bridges are made of titanium. The triangular bridge structure ensures robustness, allowing it to withstand a 5,000g shock test. The large barrel, visible from the 12 o'clock position, provides a power reserve of approximately 90 hours, and the silicon escapement can be seen from the 6 o'clock position.

This new model is announced as the world's lightest mechanical diver's watch. It features a skeleton movement that eliminates all unnecessary elements, yet remains extremely robust. Automatic winding (Cal. UN-374). 21 jewels. 21,600 vph. Power reserve of approximately 90 hours. Ti and carbon fiber case (diameter 44mm, thickness 14.7mm). Water resistant to 200m. 6,006,000 yen (tax included). (Inquiries) Ulysse Nardin/Sowind Japan Tel. 03-5211-1791
Sinn "T50 Gold Bronze B" Ref.1052.062

This rare model, limited to 300 pieces worldwide, features a vintage-inspired gold bronze case, a dark blue dial, and a blue textile strap. Gold bronze is a material developed exclusively by Sinn, a bronze alloy made from a mixture of copper, tin, and gold. Compared to regular bronze, it is characterized by its superior corrosion resistance to seawater and anti-allergy properties. The color changes gradually due to oxidation, allowing you to enjoy the changes in its appearance over time. A special cleaning cloth is included to remove any discoloration. The case back is made of titanium.
Another attractive feature is the incorporation of multiple Sinn technologies. The bezel, equipped with a unidirectional rotation prevention mechanism, uses a special screw-fastening system that secures it from the side, so there's no need to worry about it coming off even if it receives a strong shock, such as during diving. It also features Ar-Dry technology, which prevents performance degradation due to moisture contamination.
The movement is the Sellita Cal. SW300-1, which has a power reserve of approximately 50 hours. Because the movement itself is thin, the case is also only 12.3mm thick.

This is a limited edition model made with the company's proprietary gold bronze material. The case is thin and water resistant to 500m, and is equipped with a specially bonded bezel and Ar-drying technology. Automatic movement (Cal. SW300-1). 25 jewels. 28,800 vph. Power reserve of approximately 50 hours. Gold bronze 125 case (diameter 41mm, thickness 12.3mm). Water resistant to 500m. Limited to 300 pieces worldwide.

Seiko "Prospex Divers 1965 Heritage Seiko Divers Watch 60th Anniversary Limited Edition" Ref. SBDC213

This limited edition model was released to commemorate the 60th anniversary of the birth of Seiko's diver's watch. The design is based on the company's first diver's watch, the 62MAS, which was released in 1965. It inherits the iconic design, such as the linear case without a crown guard and square indexes.
The dial is the most noteworthy feature. Not only does it feature a refreshing silver dial, but it is also embossed with a wave pattern that evokes the image of powerful waves. This pattern is inspired by the wave mark engraved on the case back of the company's diver's watch. Another feature is the use of a gray bezel insert that harmonizes with the silver dial.
The stainless steel bracelet is equipped with a newly developed buckle that can be finely adjusted in six steps of approximately 2.5 mm, allowing the wrist length to be easily adjusted to suit changes in air pressure during diving or changes in physical condition in everyday life.
The movement is Cal. 6R55, which has a power reserve of approximately 72 hours.
