Strap for Seamaster 1948 Central Seconds Stainless Steel / Silver / Leather

The lug width is 18 millimetres. This specification determines the compatibility of all straps: it must be measured between the lugs of the case (the lateral attachments) with a digital caliper. An 18mm lug width excludes mass-market universal straps of 20mm, but allows access to specialized catalogues of artisanal and semi-custom straps.

For this historical reissue, a natural alligator or vegetable-tanned calf leather strap represents the most coherent stylistic choice: it amplifies the curatorial character of the Museum Collection and ages nobly over time. For versatile daily use, a NATO strap in cotton and polyester, 1.4-1.6mm thick, is practical and reversible. A structured FKM rubber is ideal for accepting sporty use without compromising construction quality.

Use a specialized tool (pin remover or strap tool) to extract the spring bars from the case lugs. Insert the pin remover into the small lateral opening of each lug, gently pushing the pin towards the centre until release. Remove the old strap and insert the new one by aligning the attachments with the case lugs, then reinsert the pins. Proceed slowly to avoid damage to the steel.

Yes, provided they respect the 18 millimetre lug width. Any artisanal or semi-custom strap designed for 18mm will be compatible. Milano Straps provides a complete collection of 18mm straps both ready for shipment and customizable in tanning, colour and dimensions specific to this model.

An artisanal quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 4-6 years of daily use, extendable to 8-10 years with regular maintenance (cleaning, conditioning, drying after moisture). The stitching area is the critical point: a strap constructed with thick waxed thread and triple-layer stitching resists ageing better. The Casati Milano atelier provides an 18-month warranty on all made-to-measure straps.
