Romain Gauthier has announced the launch of a tantalum limited edition of its most iconic timepiece, the Logical One, available exclusively in Asia, with a limited run of 18 pieces. Seeking something special for Asia, Romain Gauthier arrived at a material new to the brand: tantalum, one of the most precious rare metals, with special and unique properties. Dark gray tantalum is twice as hard as titanium and highly resistant to corrosion and scratches.
Logical One Tantalum Limited Edition
Tantalum is one of the rarest stable elements in the solar system, even less abundant than gold. Its rarity, plus its luxurious texture, make it a unique material for watchmaking. Tantalum is incredibly durable and resistant to corrosion and skin allergies. Like its namesake, Tantalus, from Greek mythology, tantalum is a unique metal that can remain submerged in water forever.
Tantalum: A precious rare metal

The Tantalum model features a Grand Feu enamel dial and a two-tone case with a tantalum caseband, and the bezel, bezel caseback, pushers, and crown are available in red or white gold.
A collector's item that gives you the joy of owning it
For the Logical One, which was launched in 2013, 2023 marks the 10th anniversary of its launch and also the end of production. In accordance with the "Legacy" concept announced last year, Logical One will accept orders for only 20 pieces each of the white gold and titanium cases by 2023, with production ending with 18 pieces of the tantalum edition, exclusive to Asia.
The year 2023, when production will end, also marks the 18th anniversary of the brand's founding. The number 18 represents the anniversary of the year in which the Logical One reaches its final production milestone. The Logical One Tantalum Edition is not only a special watch with a special mechanism and material, but also a precious piece with a special story. What's more, this model will be released exclusively in Asia, in Japan, Taiwan, and Singapore.
Pioneer of the fusee-chain constant-force mechanism
The Logical One won the Grand Prix in the Men's Complications category at the 2013 Geneva Watchmaking Grand Prix GPHG. This watch uses a unique innovation to evolve the traditional fusee-and-chain mechanism, which has been used since the days of pocket watches, into a mechanism that can be installed in a wristwatch, successfully maintaining a constant power supply while driving the movement (constant force). This groundbreaking, unique mechanism has earned Romain Gauthier worldwide recognition as a true luxury watchmaker, and the Logical One has become a timepiece of such precious value that it has become legendary for the brand.
Ergonomic push button design
The mainspring is wound by pressing the push button built into the case side at 9 o'clock, and the ergonomic design of the button makes winding a fun task.
Highest quality hand finishing
The movement is exquisitely decorated with hand-chamfered edges, frosting, snailing, hairline finishing and circular graining.
