Strap for Rectangular Complication Stainless Steel / Black - Arabic

The lug width of the Rectangular model is 23 millimetres. This specific measurement is determined by the rectangular case proportions and represents the internal distance between the two lugs where the strap attaches. You can verify this measurement using a digital calliper positioned horizontally between the springbars. Using a strap with a different lug width – either 22 or 24 millimetres – would result in instability or make mounting impossible.

For the Rectangular, a high-quality leather strap is recommended, preferably alligator or vegetable-tanned calf leather, as natural materials engage elegantly with the Art Deco aesthetics of the rectangular case. Alternatively, a robust canvas NATO strap offers practicality and versatility whilst maintaining formal dignity. For sports or aquatic use, synthetic rubber ensures durability without visual compromise. Your choice should consider strap thickness – it must not compete dimensionally with the 33-millimetre case – and colour should complement rather than contrast the neutral dial.

Strap replacement requires a specific tool: a spring bar tool, available from watch retailers or online suppliers. Position the watch with the strap facing upwards. Gently insert the flat tip of the tool under one of the tension springs and push downwards until the spring retracts. You can now withdraw the lug from the hole. Repeat on the other side. To fit the new 23-millimetre strap, first align one end into the lug hole, then use the tool to compress the opposite spring until the pin sits fully. Verify that the strap is securely fastened on both sides before wearing the watch.

Yes, numerous artisanal manufacturers produce 23-millimetre straps compatible with the Rectangular. Specialised retailers such as Milano Straps offer carefully curated selections in leather, NATO, and rubber, all specifically adapted to this lug width. Compatibility verification is essential: the strap must feature two 23-millimetre lugs with central perforation for standard springbar attachment. Avoid generic or unspecified straps, as the risk is mounting an unstable strap or damaging the case lugs.

Leather strap longevity depends on usage intensity, climate conditions, and material quality. An alligator or premium calf strap, subject to moderate wear in temperate environments, typically lasts 4–7 years before replacement is necessary. Vegetable-tanned leather develops natural patina over time, sometimes extending aesthetic appeal beyond structural functionality. The most critical factor is humidity: very humid climates or frequent water exposure reduce lifespan considerably. To extend durability, alternate between two straps, dry the watch after humid conditions, and periodically inspect the attachment point for micro-fractures. When the leather becomes stiff or visible cracks appear, replacement is advisable.
