What lug width does the Hamilton Khaki Field take?

Can I replace the bracelet on my Hamilton with a leather or rubber strap?

Yes. Hamilton uses standard spring bar fittings on all models except the Ventura. Remove the bracelet with a spring bar tool or a dedicated bracelet removal tool, fit the spring bars into the new strap, and click into place. Takes under a minute.

Do you sell Ventura straps?

The Hamilton Ventura uses a non-standard lug width due to its shield-shaped case. Most aftermarket straps do not fit the Ventura without modification. We recommend OEM Hamilton straps for this model.

What is the best strap for the Hamilton Murph?

The Murph takes 20mm. It ships on a brown leather strap which suits its Interstellar heritage perfectly. For a sportier look, try an FKM rubber strap in black. For weekends, a NATO in olive or grey leans into the field watch character the Murph was designed around. All Hamilton straps ship with spring bars. Free UK delivery on every order. 30-day returns.
