The Icons of Favre-Leuba

The Raider Harpoon, the Bivouac 9000 and the Bathy 120 MemoDepth, together exemplify the ingenious engineering that is unique to Favre-Leuba. The second oldest Swiss watch brand introduced these in 2016, 2017, and 2018 respectively and the instrument watches, also known as ‘The Icons’ of Favre-Leuba’, are used by explorers from sea to summit voyages. The rugged form and robust functionality make them indispensable companions for those who conquer frontiers


The brand that was born in 1737 introduced a new collection of watches in the recent years. After the long silence, the new range of retro-futuristic instruments were inspired by the legendary timepieces from 1960s, but in a more contemporary style and design DNA. With the launch of Raider Harpoon, Raider Bivouac 9000, and Raider Bathy 120 MemoDepth, three iconic watches launched year after year, the brand created a benchmark in the industry once again. These three unique Icons are one of its kind, and surpass any other diving or altitude watch the world has seen.

Bivouac 9000

1964, Walter Bonatti, one of the most successful mountaineers of all time is climbing in the Grand Jorasses. Faced with an impending storm, he turned to his Bivouac to gauge his distance from the summit. In a potentially life-saving decision, he sought out a safe area to create shelter from the storm. He knew from the altimeter reading on his Bivouac that it was too far to climb to reach the summit and safety in such drastic weather conditions.

In 2018, the iconic watch was re-engineered with contemporary technology and introduced back into the alpine world. However, this time the Bivouac is galvanized out of tough, but lightweight titanium and it is more robust than ever. Furthermore, it is ready to read and display the altitude and air pressure conditions to 3 times higher than of what its predecessor did. The new Bivouac 9000 measures the altitude from below sea level to 9000m, which is beyond the roof of the world. The 48mm diameter barrel-shaped case is crafted to the highest level to protect the inner mechanism of the watch. Inside, you will find a manual-winding FL311 movement. The innovative capsule used to measure the air pressure is made of new materials and the precise design allows it to measure minor changes in the surrounding atmospheric pressure, to convey the changing weather and the altitude thereof. This is the heart of the Bivouac altimeter technology. As the mountaineer ascends, the surrounding air pressure decreases and so the aneroid capsule expands. This incredibly small linear movement is translated via a mechanism onto the face of the watch to indicate both air pressure and altitude readings.

In its short history, the new Bivouac 9000 has been awarded the independently judged New Star Award 2018. Adrian Ballinger, a renowned mountaineer, summited Everest earlier in the same year wearing the Bivouac 9000. Securing the title as the first altimeter wristwatch to precisely convey a correct altitude reading all the way to the top of the world at 8,848m.

“At 8800m - my Raider Bivouac 9000 performed flawlessly all the way to the summit of Mt Everest” Adrian Ballinger, 20th May 2018.

Bathy 120 Memodepth

In 1968 came the release of the world's first dive watch with a built-in depth gauge. The Favre-Leuba Bathy had delivered truly pioneering technology, allowing divers to gauge their descent below the ocean. In addition, this critical information was essential to assisting divers with their decompression zones before resurfacing.  

In 2018 our objective was to not only re-introduce the Bathy but deliver a highly sophisticated dive-watch that would truly match the level of diving exploration we see in the ocean today. The Bathy 120 MemoDepth uses similar technology to that of the Bivouac 9000. However, with a subtle yet crucial differences. The back of the case shows small, precisely crafted openings in the style of the Favre-Leuba hallmark. These openings let in ocean water and thus allow the dive watch to measure water pressure, but protect the movement of the watch with hydrophobic sealing. As the diver descends, water pressure increases and the specially engineered membrane alters shape. The degree of change in the membrane is calculated mechanically, and the information is then translated to the watch face. As a result, the diver can quickly observe their depth down to 120m. The 200m water resistant dive instrument hence not only displays dive time and depth, but also records the maximum depth. On resurfacing, the diver can notice the lowest point of the dive. All done mechanically.

The watch face is highly legible with a range of indicators. Such as the 20-minute scale on the unidirectional rotating bezel, dive depth quadrants on the dial, and red decompression stop indications. Furthermore, the bright luminous hands and indices increase the ability to sight for readings in the dark depths. Whereas the intelligent use of color shading on the face helps to signify greater depths. Similarly, the blue center-mounted hand sharply draws the eye to the current depth reading. Above all, the wristwatch is once again robust and enduring. This is exemplified by our use of grade-5 titanium to craft a sturdy 48mm case that is designed to ensure it does not feel too big on the wrist. The fit on a thick wet suit and also on the bare wrist is great, and the size allows ease of reading of dive information at great depths. As a result, the Bathy 120 MemoDepth is a dive watch built to conquer ocean frontiers.

Professional Dive explorer Florian Fischer from Behind the Mask team says - The Bathy 120 Memodepth is a great, multifunctional diving watch. Ideal for adventurers and divers that have exceptional demands when it comes to design and functionality. Having used it in extremely cold waters of Norway, and also in the warm waters of Bahamas, the instruments ability is noteworthy. Regular divers find that the aperture in the case back also allows ease of cleaning of the membrane when it is frequently exposed to the saline ocean water, a feature most dive watches lack thus making maintenance difficult in the long run.

Raider Harpoon

The Raider Harpoon was originally launched in 2016 and created a lot of buzz with its unique method to display time. in 2019, it comes with a brand new look. The case has been modified, and the new design of the lugs allow for a superior fit. Next, not only the central dial, but also the hour display ring is now black. This offers a more distinct and sharp style to the watch. In addition, a matt finish of the PVD gunmetal has been added to deliver a robust feel.

The Raider Harpoon model was inspired by the 1960’s Deep Blue dive model. The timepiece stands out for its bold colors and heritage barrel-shaped case. With the single minute hand and the co-rotating hour ring, the innovative method for displaying time ensures ease of reading during a dive. Even on dry land, the watch with a single hand ensures you only have to look at one point to read the precise time as this indicates both the minutes and hours. As the minutes tick away, the hours are displayed on the co-rotating disc visible on the edge of the dial, which has a blue emission luminous display, ensuring great visibility even in the dark. This means that one very quick glance you can sight both the minutes and hours from the one hand no matter the surrounding light conditions. The reason for engineering this method of time display is that elapsed minutes is the most crucial information for a diver, therefore the minute reading is front and center on the face of the Harpoon. This also prevents the confusion caused during the overlap of the hour and minute hands, that can be fatal during diving. Furthermore, seconds are displayed using a function control central rotating disc. 

Powering the Harpoon is the patent pending, reliable Automatic FL301 movement. This is based upon the Sellita SW200 ­caliber. The movement is protected in a 46 mm case, with a screwed in back. The case also has a screwed down crown, helium valve, and thick sapphire crystal. All of this enables a water resistance rating of 50 bar / 500m. In addition, the watch features a stainless-steel, unidirectional bezel. This has a 20-minute marked dive scale on it, which is visible on the anodized aluminium insert. An essential tool for keeping track of dive times. Furthermore, Super-LumiNova is not only applied to the hour ring, but also to the minute hand and the central function control disc. As a consequence, you can view the functioning watch face clearly in the dark. The extreme lume used on the Harpoon assists deep ocean divers as the light begins to dim below 50m.

Pen Hadow used the Harpoon to great effect on his latest Arctic research mission. “Watch-making and exploration became closely entwined when accurate timepieces developed beyond timekeeping and became instruments to reckon with in the deep unknown” - Pen Hadow
