Hamilton Khaki Field Mechanical Power Reserve 40mm Watch Straps and Bands

Replacement watch straps and bands for the Hamilton Khaki Field Mechanical Power Reserve 40mm — reference numbers H69509110, H69509130, H69509910 and H69509930.

Select 20mm to ensure it fits your watch. That is the gap between the lugs, not the case diameter. A strap wider than 20mm will not go in, and a narrower one leaves a visible gap either side.

Standard straight lugs and spring bars, so any 20mm straight-ended strap on this page will fit — no adapters or proprietary connectors needed.
