Highly reliable timekeeping devices for divers are a separate caste of high-end watches produced by the world-famous brands. The most memorable diving models presented this year at Baselworld are wristwatches from the Tudor Black Bay line and a bold timepiece from Longines.

Longines HydroConquest Ceramic

Ceramics as a high-tech and scratch-resistant material, which until recently was a distinctive feature of expensive high-end watches, begins to make its way into the class of lower-cost models. Using the developments of the Swatch group in the production of ceramic cases, the brand from Saint-Imier demonstrates a new model in the HydroConquest collection of diver timepieces.

Longines HydroConquest Ceramic

Black zirconium ceramics is used here not only for the 43-mm case ring and the lugs but also for other important elements. Among them are a unidirectional bezel, a solid back cover, a screw-down crown, as well as a matte dial marked with the ZrO2 thematic marking. This top-notch timepiece from Longines is incredibly watertight – around 300 meters.

The deep black color of the dial contrasts favorably with the silver-applied indexes and hands using the white SuperLumiNova luminescent composition.

The three-hand indication of the date is based on the automatic caliber L888.3 (created on the basis of ETA A31.L02) with a 3.5-Hz balance and a power reserve of 65 hours.

The black rubber strap features a folding clasp with double protection and the possibility of precise adjustment completes the image of this stylish wristwatch.

Tudor Black Bay P01

In 1967, the watch producing company from Geneva, which at that time was a supplier of diving watches for the U.S. Navy, began working on the project “Commando.” Tudor masters were planning to create a new, more advanced model, the first prototypes of which appeared a year later, in 1968.

Fate decreed otherwise, and the U.S. Navy eventually opted for Ref. 7015 from the current Tudor catalog of that time. The Commando prototypes migrated to the archives of the company until their recollection 50 years later. This high-end watch laid the basis for the creation of the new Black Bay series representative.

The timekeeping device shown at Baselworld 2019 is set in a 42-mm satin steel case with 200-meter water resistance. The layout of the historical predecessor is seen in the characteristic 4-o’clock position of the screw-down crown and in the presence of a lifting bracket at 12 o’clock. The latter blocks the rotation of the bidirectional bezel.

The black dial with a central three-hand display and date indication offers recognizable hour indexes with an abundance of luminescent composition and signature “snowflake” hands.

The perfect addition to this tech-savvy construction is the automatic caliber MT5612 certified as the official COSC chronometer. This timepiece mechanism also ensures a 70-hour power reserve combined with a 4-Hz balance with a silicon spring.

As the final chord to this masterpiece, the Tudor company offers a combined strap made of brown calfskin (with contrast stitching) on a black rubber base. It was created specifically for the Black Bay P01 high-end watch. The steel elements adjacent to the watch case represent the binding element with its historical prototype created over 50 years ago.
