Rectangular 01 561 7692 4031-07 8 18 20— lug 18mm

The lug width is 18 millimetres, a non-standard measurement requiring specialised strap suppliers. To verify, remove the current strap and examine the inner side of the lug, where the width is engraved.

We recommend alligator in dark tones (black, walnut brown) for formal wear, vegetable-tanned calf for noble patina, shell cordovan for tactile sophistication, or cotton NATO for vintage-modern versatility.

Use a spring bar tool to remove the bars from the lugs. Insert the tool into the small slot beneath each lug, lift gently to free the metal bar, then slide out the old strap. Align the new strap's holes with the lugs, reposition the spring bars until they click into place.

Absolutely. An artisanal leather strap of superior quality significantly elevates the aesthetic and tactile value of the watch. Choose specialised suppliers guaranteeing precision on the 18mm lug width and construction with double stitching.

A vegetable-tanned leather strap lasts 3-5 years in daily use. Longevity depends on care, sun exposure, and humidity. The patina that develops is part of its appeal—leather ages nobly. Alternatives like shell cordovan last up to 7 years thanks to superior material density.
