Strap for Step One Day & Date Stainless Steel / Black

The lug width of the S1302 is 20 millimetres. This measurement is specific to the model and is essential for aftermarket strap compatibility. Precise measurement with a metal ruler inserted into the lug attachment ensures absolute compatibility with any quality strap.

For the S1302 we recommend an authentic alligator strap with vegetable tanning, which elegantly dialogues with the sculptural geometry of the case. Alternatively, a high-density NATO strap offers versatility, or a calf leather with vegetable tanning for those seeking softness. For sports use, a quality FKM rubber strap maintains correct visual proportions.

The change requires a spring bar tool to remove the elastic lugs that retain the current strap. Position the tool under the lug, apply gentle pressure to make it retract, then remove the strap. Insert the new strap into the upper spring, then position the lower spring. Verify that both attachments are firmly seated before use.

Yes, provided the strap is specifically constructed for 20mm lug width. For compatibility to be guaranteed, the internal diameter of the attachment must correspond exactly to 20 millimetres. Straps of 18mm or 22mm will not fit correctly. We always recommend verifying the manufacturer's technical specifications before purchase.

A quality leather strap, with vegetable tanning, used daily has an average lifespan of 2–4 years before requiring replacement. Longevity depends on sun exposure, humidity, frequency of use and maintenance. A strap born from tannin, with intact grain, acquires character and patina over time, becoming more personal with conscious wear.
