A reboot of the classic pilot watch, the Ace was designed for versatile style and legibility at a glance.  Features include large Arabic numerals at 3, 6, and 9, with a unique arrow indicator at the 12 o’clock position. Luminous indicators on the dial allow for easy reading.  A screw-down crown keeps water out to depths up to 100 meters and the full exhibition case back displays the finished movement inside.

Your customized Ace will be assembled and shipped within 5 business days from the time of your order.

Cleaning and Maintaining Your Watch
You don’t need to do much. Every few years, it’s a good idea to bring it for a tune up and lubrication check at your local watch repair shop. Clean with soap and water or a dry cloth as needed. Avoid getting leather straps wet, and make sure you tighten the screw down crown before submerging.
