Strap for Khaki Field Mechanical Power Reserve Stainless Steel / Black / Bracelet

The Hamilton Khaki Field H69509130 features 20mm lugs. This size is the standard for the model and allows the use of any aftermarket 20mm strap without requiring adaptations. To verify, measure the distance between the two attachment holes on the inside of the lug: you will obtain exactly 20mm.

For this military Field, straps in natural alligator with vegetable tanning, calf leather with vegetable tanning in oxblood brown tone, or NATO straps in canvas khaki or grey tortora are recommended to emphasise the tactical origin. A natural rubber strap is ideal for those who practice sports or work in humid environments.

Changing the strap is simple and requires no case modifications. Use a spring bar removal tool to gently push the pins that secure the strap to the case lugs. Once removed, disconnect the old strap and insert the new one, ensuring the pins seat correctly in the attachment holes. The operation takes less than 5 minutes.

Yes, the Hamilton H69509130 is fully compatible with any 20mm aftermarket strap. The standardisation of lug width guarantees perfect attachment without modifications to the case. We recommend verifying that the strap is manufactured to professional construction standards to ensure durability over time.

A natural leather strap, whether vegetable-tanned or alligator, typically lasts between 3 and 5 years of daily wear, provided it is exposed to moderate humidity and receives regular maintenance: cleaning with a soft dry cloth and annual conditioning with natural oils. Natural ageing of leather is not deterioration but the development of a personal patina that increases the aesthetic value of the strap.
