Black Buttero Strap for a Hamilton Khaki Field
Share
The Hamilton Khaki Field is a no-nonsense military-style watch, and a black Buttero leather strap suits its utilitarian character while adding a touch of quality. This owner in Washington had one built for their 42mm H706050 at 75/115mm with black stitching. It was cut to order for the case and wrist.

Why these choices
Buttero is a dense veg-tanned leather from the Walpier tannery in Tuscany, firm and smooth, and it patinas with use rather than wearing out. That toughness suits a field watch built to be knocked around, and black keeps it versatile, working as easily with casual clothes as with something smarter. Black side stitching keeps the look quiet and utilitarian, in step with the Khaki Field's military roots.
The 20 mm buckle width matches the case, and the tapered tip keeps the strap from looking slab-like on the wrist. The 75/115 mm length was cut to fit, and regular spring bars keep it easy to service or swap with a tool.

★★★★★
“Watch band was a perfect fit, of high quality material and build, looks and feels better than original strap for a fraction of the cost. Delivered as planned and communication with vendor was on point!”
