Strap for D15 MK-1 Titanium Grey Gold / Black

The lug width of the D15 102-GJLA is 20mm. This is the distance between the case lugs where the strap attaches. This measurement is industry standard and allows broad compatibility with quality aftermarket straps.

We recommend straps in natural alligator, vegetable-tanned calf leather, or superior shell cordovan for the D15 102-GJLA. The bicolour titanium and white gold case requires noble materials that maintain aesthetic balance. Recommended colours: black, deep brown, pearl grey, or ivory white.

Remove the strap using a strap changing tool or thin, flat blade positioned gently under the lug to lift the spring bar holding the strap. Reverse the process to fit the new strap, ensuring the spring bar is fully inserted and locked in position.

Yes, the D15 102-GJLA accepts aftermarket straps with standard 20mm lug width. However, we advise against low-quality straps as the bicolour case and sophisticated geometry require artisanal materials that match the watchmaking standard of the timepiece.

A superior quality leather strap (alligator, vegetable-tanned calf, shell cordovan) lasts 3-5 years with daily use, developing progressive aesthetic patina. Lifespan depends on humidity, frequency of use, and maintenance. Vegetable tanning tends to age more elegantly than synthetic tanning.
