Strap for Khaki Field Quartz 33 Stainless Steel / White

The lug width is 18mm. This specific measurement is a constructive feature of the 33mm model and is measured from the inside of one spring bar hole to the inside of the other, on the inner side of the case. It is a non-standard dimension in contemporary watchmaking, therefore careful selection of the strap is required.

The choice depends on intended use and personal aesthetic. A vegetable-tanned alligator in cognac tone emphasises the military heritage; a vegetable-tanned calf in black offers formal elegance; a NATO strap in oiled canvas with a sand grey tone restores vintage authenticity; FKM rubber in grey is ideal for daily wear and sport. The neutral colour palette of the 33mm stainless steel allows versatile pairing.

Remove the spring bars securing the old strap using a spring bar tool, gently inserting the lever under the lug. Extract the bar from the opposite side and repeat for the other side. Insert the new strap's bars into the case lugs, ensuring they are correctly aligned. Never force: the operation requires calibre and patience.

Yes, provided the lug width is exactly 18mm. Many artisanal and industrial quality straps are manufactured in this size. Always verify technical specifications before purchase and choose suppliers that guarantee precise tolerances. The quality of the leather and spring bar finishes influence the final result.

A vegetable-tanned calf strap, with regular maintenance (gentle cleaning, drying after moisture exposure), lasts 3-5 years. Duration varies based on daily use, personal perspiration and climate conditions. Rubber and NATO materials prove more resistant over time, whilst shell cordovan tends to improve with natural ageing.
