UR-103T Mexican Fireleg Limited Edition: The Swan Song of the UR-103 Collection.

Introducing the UR-103T Mexican Fireleg, one of the final masterpieces of the UR-103 collection, produced in a limited edition of just 60 watches. Named after the striking Mexican Fireleg Tarantula, this timepiece features an all-black steel and titanium case with our advanced AlTiN (aluminium, titanium, nitride) coating, providing a deep black backdrop that accentuates the bright, venomous orange luminescent markings.

The Mexican Fireleg stands out with its sleek, aggressive, and dangerous design, distinguishing itself from its shinier precious metal siblings. Rarely seen on the open market, the Fireleg was extremely popular upon its original launch. If you missed out the first time, now is your chance to add this rare piece to your collection.

The front of the Fireleg showcases a predominantly sapphire crystal design, a characteristic of the Tarantula variant, which opens up the case and dial to reveal the intricate dance of the four orbiting satellites. Each satellite carries three-hour markers that begin their silent journey across the minute track from east to west at the start of each hour, mimicking the movement of the sun.

Flip the UR-103T over to discover the 'control board' on the case back. Here, you'll find a 36-hour power reserve indicator, 15-minute and second dials for precise time-setting, and a user-adjustable fine-tuning screw. At its heart is our manual wind calibre 3.04, a testament to URWERK's commitment to horological excellence.

Don't miss this opportunity to own a piece of URWERK history with the UR-103T Mexican Fireleg Limited Edition, a watch that truly embodies the spirit and innovation of the UR-103 collection.
