Favre-Leuba Raider Bathy 120 MemoDepth


Favre-Leuba, the second oldest Swiss watch company, has recently launched a very special timepiece – the Raider Bathy 120 MemoDepth (ref. 00.10108.06.51.31). The watch celebrates the 50th anniversary of the brand’s iconic Bathy, the world’s first mechanical wristwatch that could measure and display both dive time and current depth. The Bathy represents a milestone in the development of mechanical instrument watches. Named after the Greek word for deep, it is highly sought after by collectors today.

The new Favre-Leuba Raider Bathy 120 MemoDepth features a depth gauge that works on a similar principle as the one on the original model. On the back of the watch there are openings that allow for water to enter. The water cannot harm the movement since the depth gauge is hermetically separated from it. Once the water has entered, it goes to a separate chamber and causes a specially designed membrane to compress as the pressure increases. As a result of this, a mechanical contact sensor reacts and transfers the information to the central blue hand, which indicates the dive depth on a nonlinear display on the dial.

The depth scale is finer for the first 30 meters

 

The scale for the first 30 meters is finer, with two red marks (5 and 10) where decompression stops are required. Water resistant to 200 meters, the Raider Bathy 120 MemoDepth can precisely measure depths of up to 120 meters. If the wearer dives deeper than that, a built-in mechanical limiter will ensure that neither the membrane nor the depth gauge are damaged. Thanks to its mechanical depth memory (MemoDepth), the watch can save the maximum depth reached during a dive. The value is displayed on the 3 o’clock sub-dial until it is reset using the screw-in pusher at 4 o’clock. In addition to depth, the dial also displays hours, minutes, small seconds at 9, power reserve at 12, and date at 6 o’clock.

The new Favre-Leuba Raider Bathy 120 MemoDepth is housed in a large 48mm titanium case. According to the Swiss brand, its design is a homage to the original model. Like a true diving piece, the watch features an external dive bezel which allows the wearer to track their remaining time. If a diver were to accidentally bump their watch against something, this could change the bezel’s position and alter his/her settings. However, with the Raider Bathy 120 MemoDepth, this isn’t a big issue since its bezel can only be turned counterclockwise. This means that the diver cannot make any dangerous miscalculation of the dive time because moving the bezel in this case would only subtract from the planned dive time. The divers can simply surface earlier than intended, thereby potentially preventing  a decompression stop.

Ticking inside the new Raider Bathy 120 MemoDepth is the hand-wound caliber FL321. This ETA-based movement runs at 28,800 vibrations per hour and offers a power reserve of approximately 65 hours. Completing the latest Favre-Leuba watch is a sporty black rubber strap with titanium pin buckle. The watch retails at CHF 8,500.
