Strap for Speedmaster Reduced Stainless Steel / Red / Strap / Schumacher

The lug width of the Speedmaster Reduced 3810.61.41 is 18 millimetres. This non-standard measurement in the mass market maintains the proportions of the 39mm case. It is measured with a digital calliper between the two internal lug pins, without confusing it with the length of the pins themselves (2.2mm on this model).

For the sport-classic profile of this chronograph, dark brown alligator with a deployant clasp is the choice of maximum aesthetic coherence. Alternatively, satin calf offers natural ageing and patina development. For robust daily wear, NATO straps in fabric or Fluoro-elastomer rubber straps guarantee practicality without visual compromise.

Remove the pins that pass through the lug using a spring bar tool (a small dedicated lever). Position the tool under the pin, pushing gently to release the internal springs, then extract the pin from the hole. Slide off the old strap and insert the new one by aligning the lug holes with the pins. Press the pin until you hear the click that confirms it is locked in place.

No, because the 18mm lug width is exclusive to this model. Most other Omega watches and sports chronographs use 20mm lugs. A 20mm strap does not fit the lugs of the 3810.61.41. Make sure to purchase straps specifically designed for 18mm lugs.

A quality alligator or calf strap, used in rotation with at least one other option, lasts between 3 and 5 years before needing replacement. Exclusive and intensive use shortens the cycle to 18-24 months. The leather wears from the wrists due to friction and perspiration. Casati Milano guarantees 18 months on bespoke straps made in the atelier, with the possibility of regenerating the leather before expiration.
