2025 Longines Legend Diver 39mm

Longines Legend Diver - Mastering the depths this summer with three new models

Fusing timeless heritage with contemporary vision, Longines is expanding its legendary diving watch collection for 2025. The Legend Diver adds a striking new matt white dial model and introduces versatile blue and black rubber straps. These new additions continue the legacy of Longines' iconic diving watch first introduced in 1959, combining design elegance with cutting-edge performance.

Evolving with precision for over six decades, the Longines Legend Diver stands as a testament to the brand's commitment to both innovation and tradition in quality diving watches. The latest chapter in this storied collection introduces a model with a striking new matt white dial alongside two new rubber straps. Instantly recognizable by its dual crowns and internal rotating bezel, this emblematic timepiece unites more than six decades of diving heritage with contemporary precision and timeless design.

For 2025, the Swiss watchmaker has introduced a model featuring an immaculate, matt white dial that provides exceptional contrast and readability, while maintaining the distinctive DNA of the collection. The hours are marked by extended indexes and raised Arabic numerals, complemented by satinated black and light green arrow hands, all treated with Super-LumiNova® to ensure optimal visibility in all conditions. This pristine dial is protected by a domed sapphire crystal with black-metallic coating and multi-layer anti-reflective treatment on both sides. The watch comes with a stainless-steel bracelet with beads-of-rice links at the centre, providing exceptional flexibility and comfort on the wrist. The bracelet also features a micro-adjustable, doublefolding safety clasp for a refined aesthetic that balances technical performance with understated elegance.

Complementing the collection are two models featuring either a lacquered blue dial or a lacquered black dial, now paired with matching blue or black rubber straps, respectively. These expand the already diverse Legend Diver lineup, which previously offered these distinctive dials with a stainless steel bracelet or leather or nylon nato straps. Combining comfort, durability and style, rubber bracelets are a must-have for every occasion in 2025. The addition of this option provides a contemporary look that combines the durability of rubber with the sophistication of the Legend Diver design. Each new strap features a diver pin-buckle that ensures a secure fit whether exploring the depths below or enjoying adventures on land.

All three timepieces maintain the sleek 39 mm stainless-steel case with alternating polished and satin finishes. The internal bidirectional rotating bezel—a revolutionary feature first introduced by Longines in 1936—remains protected inside the case and is operated by the screw-in crown at 2 o’clock, which activates it on a 60-minute scale, graduated on the flange and topped with a luminescent triangle symbol. This innovative design not only continues the heritage of the original model but also provides practical protection against accidental manipulation or shocks.

In keeping with Longines' commitment to exceptional performance, these watches are certified as diving watches (ISO 6425) with water resistance up to 30 bar (300 metres). The entire Legend Diver watch is also fully chronometercertified by the COSC (Contrôle Officiel Suisse des Chronomètres), ensuring superior accuracy in all conditions. It is powered by the exclusive Longines calibre L888.6 with silicon balance spring and innovative components, providing a magnetic resistance ten times greater than the ISO 764 reference standard. These exceptionally precise automatic watches have up to 72 hours of power reserve.

With its blend of heritage-inspired design and cutting-edge technology, the expanded Legend Diver collection continues to exemplify Longines’ philosophy that elegance is, indeed, an attitude, one that transcends time and remains as relevant today as when the original model first appeared over six decades ago.

From the first water-resistant models to the Legend Diver

The Swiss watch brand began producing its first water-resistant watches in the 1910s. In 1937, it launched the first chronograph with water-resistant pushers, which it patented the following year. In the 1940s, Longines helped the UK Hydrographic Institute design the very first diving wristwatches for Royal Navy divers. Previously reserved for the military and scientists, diving subsequently opened up to the public, who began to appreciate it more and more. Deep-sea exploration was becoming more accessible, attracting a growing number of enthusiasts. As well as aqualungs, regulators, masks, and fins, diving requires technical equipment including a depth gauge, a pressure gauge, and a reliable divers’ watch for measuring immersion times accurately.

At the end of the 1950s, Longines began producing divers’ watches. These instruments followed in the footsteps of those manufactured by the brand throughout its history for countless pioneers at sea, on land, and in the air. In 1958, Longines introduced the Nautilus Skin Diver. It had a case that was waterresistant up to 12 bar (120 m) and a steel bracelet with a fine-adjustment system for wearing over a diving suit. In 1959, Longines developed what was to become the Legend Diver: a model specifically designed for underwater exploration, water-resistant up to 12 bar (120 m). To avoid exposing the external rotating bezel, the Longines technicians decided to move it under the glass to protect it. This internal bidirectional rotating bezel is an ingenious feature invented by Longines in 1936, and the Legend Diver was the first divers’ watch to feature it, inspiring many other watch brands. It was operated by an additional crown at 2 o’clock, all protected by a revolutionary Super-Compressor case. Over the course of the 1960s and 1970s, water-resistance was further improved with several generations of models.

In the 2000s, the brand revived this iconic watch by including it in its Heritage segment. Today, the Longines Legend Diver combines cutting-edge technology and iconic design while celebrating a unique history.

Divers’ watch certification (ISO 6425)

The ISO 6425 standard is established by the International Organization for Standardization (ISO) and specifies the criteria and requirements for divers’ watches and deep-diving saturation divers’ watches. According to this standard, a divers’ watch must be water-resistant to a minimum hydrostatic pressure equivalent to 10 bar/100 metres (the immersion test must be carried out with an excess pressure of 25% as compared to the water-resistance required), be resistant to shocks, magnetic fields, condensation, corrosion and temperature variations, be fitted with a secure dive time indicator (e.g. rotating bezel) and offer optimum readability in the dark by means of luminous indicators (e.g. luminescent hands).
