Dating from c.1940-41, with a stainless steel case and a canvas strap, the manually wound watch ref CK2129 has a bi-directional rotating bezel with a currently non-working locking function.
According to Miller & Miller’s Ethan Miller, it is an example of the type of original watch that is becoming increasingly hard to find, resulting in a double-estimate final price of Can$7000 (£4140).
