Strap for TT1 Worldtimer Stainless Steel - Rubber / Black / Rubber

The Oris TT1 01 690 7527 4464-07 4 features a 24mm lug width, measured from the centre of the upper attachment hole to the centre of the lower attachment hole. This specification is critical when sourcing aftermarket straps, as lug widths of 20mm, 22mm, or 26mm will not fit correctly into the case lugs.

For the Oris TT1 01 690 7527 4464-07 4, the optimal strap depends on intended use: vegetable-tanned Tuscan leather (Testa di Moro shade) offers aesthetic balance and natural patina development; NATO fabric straps provide tactical practicality and complete water resistance; FKM elastomer (Fluoroelastomer) represents the pure motorsport choice, resistant to motor oils and extreme humidity. All are available in 24mm width.

Strap replacement requires no professional tools: position the watch face-down, locate the lug holes on either side of the case, carefully insert a flat tool (plastic spring bar tool or strap changer) into the hole to depress the spring bar, remove the old strap, align the new 24mm strap with the lug holes, and reinstate the spring bar. Work methodically to avoid scratching the rubber case. If uncertain, entrust the operation to an authorised service centre.

Yes, numerous manufacturers produce 24mm straps in leather, NATO fabric, elastomer, and technical materials. Verify that the strap specifies exactly 24mm lug width and that the spring bar diameter matches Oris specifications (typically 1.5mm or 1.8mm). Milano Straps curates a selection of 24mm straps engineered for technical watchmaking, with rapid dispatch and customisation options.

The lifespan of a vegetable-tanned leather strap on a technical watch like the Oris TT1 ranges from 2 to 5 years, depending on exposure to humidity, heat, and mechanical stress. Daily use in humid environments or during intense physical activity accelerates fibre degradation. Periodic maintenance—cleaning, drying after perspiration, protection from direct sunlight—significantly extends service life. FKM elastomer, by comparison, persists 8–10 years without aesthetic degradation if not exposed to extreme temperatures.
