Bremont Altitude 39 Date

Owners and reviewers widely praise the Bremont Altitude 39 Date as a sleek, legible, and everyday-suited pilot's watch, noting its comfortable 39mm 904L steel case and clean dial design.

Oak & Oscar The Jackson Big Eye is praised for its balanced design and fine details, featuring a prominent "Big Eye" 30-minute sub-register for improved readability, reminiscent of vintage chronographs. It is powered by the Eterna EMC 3907M manual wind movement with a 60-hour power reserve, column wheel, and flyback function, housed in a 40mm stainless steel case. This limited edition of 50 pieces was priced at $3,150 and included two Horween leather straps and a wallet.
