The high-accuracy two-hand quartz movement, hand-assembled in Detroit with Swiss and other imported parts, drives the hours and minutes with precision.
The Bike Lock 20mm
The Bike Lock watch is tribute to the wheeled works of art that gave us our wings. Gentle oval bends and straight-away lines define the minimal 20mm Bike Lock. Slender and elegant, the unique Bike Lock bars elongate the face shape and turn this timepiece into a talking point. A radiant Petoskey stone dial and stainless steel case are complemented by the premium leather strap.
The Petoskey stone is a treasure sought out by many who visit the beaches of northern Michigan. Varied on the surface, each stone is a fossil of colonial coral believed to have lived in waters more than 350 million years ago—and no two are alike.
Note: Petoskey stone can vary in pattern and color. No two are the same.

THE ARGONITE 751

STAINLESS STEEL
Crafted from PVD gold plated stainless steel, this elegant timepiece is built to last. Sapphire crystal, second only to diamond in hardness, protects the watch from scratches.

STONE OF THE RISING SUN
Due to the variation of Petoskey stones, every timepiece is as unique as the owner who wears it. A quick glance at the time is all you’ll need. But it’ll never feel long enough.

SMOOTH PREMIUM LEATHER
Crafted from premium leather, the leather strap lends a natural lived-in feeling to this future heirloom. It will patina beautifully with time, becoming unique to the owner.

WORTHY OF WHAT IT HOLDS INSIDE
Made with care, this leather watch box is worthy of the treasure it protects. Natural grain leather and a soft-to-the-touch interior keep your timepiece safe for generations to come.
