This high-accuracy quartz movement—hand-assembled in Detroit with Swiss and other imported parts—drives the hours and minutes with precision.







The Derby 30mm - Petoskey Stone
The perfect showcase for a one-of-a-kind stone, Derby’s case wraps elegantly around the Petoskey dial like two horseshoes. 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.
Slim gold hands and polished gold numerals complete the look. A five-link bracelet, crafted from PVD gold stainless steel, makes this Derby a true winner with an everyday elegance.
Note: Petoskey stone can vary in pattern and color. No two are the same.
