Strap for De Ville Trésor Master Chronometer Stainless Steel / Silver

The lug width of the Omega Trésor 435.13.40.21.02.001 is exactly 20 millimetres. This measurement indicates the distance between the two attachment pins (lugs) where the strap anchors to the case. Any replacement strap must respect this width with a maximum tolerance of ±0.5mm to ensure perfect fit without excessive play.

For the formal character of the Trésor 435.13.40.21.02.001, we recommend alligator in dark brown or black with white stitching thread, or vegetable-tanned calf with natural patina. If you seek maximum refinement, burgundy shell cordovan delivers brilliance without compromising the watch's aesthetic severity. Avoid NATO straps or rubber: they would completely betray the Dress Watch identity.

To change the strap you need a spring bar tool to remove the pins. Locate the two side lugs where the strap is attached, gently push the pin towards the centre of the case with the tool until the internal spring disengages, then extract the strap. Proceed identically on the second side. Inserting the new strap follows the reverse path: align the ends to the lug holes and press the pin until you feel the closure click.

Yes, any strap with a 20 millimetre lug width is compatible with the Omega Trésor 435.13.40.21.02.001. However, we recommend verifying that the width does not exceed 2 centimetres at the ends to avoid friction in the lug slots. On milanostraps.it you will find a wide selection of 20mm straps in alligator, calf and shell cordovan, customizable in colours and stitching thread.

A quality leather strap, with vegetable tanning, lasts approximately 3-5 years of daily wear, depending on frequency of use and care. The leather becomes soiled, absorbs moisture and sweat, therefore benefits from regular cleaning with a soft cloth and dry air. Shell cordovan lasts longer thanks to the dense fibre structure. To extend longevity, rotate different straps avoiding the same one every day, allowing the leather to breathe and dry completely between uses.
