Strap for Spacemaster Z-33 Titanium / Black / Bracelet

The lug width is 20mm. It is measured at the narrowest point between the two shoulders of the case, where the original strap attaches. This standard is common to many professional Omega watches and ensures wide availability of compatible aftermarket straps.

It depends on your use. For an elegant-technical profile, we recommend dark brown vegetable-tanned alligator or grey-smoke calf leather. For maximum water resistance and resistance to weathering, a military NATO or FKM rubber are the most intelligent choice. The titanium case enhances colour contrasts, so dark brown or navy blue will create very striking visual dialogues.

The X-33 uses a straight spring bar attachment. You need a strap removal tool or precision instrument to compress the internal spring of the pin and free the strap from the lugs. The pin diameter is 1.8mm. We advise against DIY if you lack experience: contact an authorized Omega service centre or a specialized watch shop.

Yes, the 20mm lug width is well served by the market. Brands such as Hirsch, Barenia, Tropic and artisan Italian manufacturers (such as Milano Straps) produce certified quality leather and rubber straps, compatible and often superior to original Omega straps in terms of aesthetic craftsmanship and customization.

A high-quality alligator or calf leather strap, with regular maintenance (periodic cleaning, drying after water contact), lasts 2-4 years of daily use. Vegetable-tanned leather ages more visibly, developing a fascinating patina. Rubber or NATO straps last 3-5 years before requiring replacement due to material degradation.
