Strap for Mini Trésor Quartz 26 Stainless Steel - Diamond / White Enamel

The lug width of the Omega Trésor 428.18.26.60.04.003 is 13mm. This undersized dimension, compared to standard women's watches (typically 14–16mm), requires straps specifically constructed for this measurement. Milano Straps maintains a dedicated 13mm collection, verifiable by manually measuring the internal space between the case lugs with a digital calliper.

Brushed alligator in grey-beige or dark brown tonality pairs ideally with the steel case and grey-tortoiseshell mother-of-pearl dial, maintaining stylistic coherence. Alternatively, smooth calf leather waxed in smoke-grey or red-burgundy shell cordovan offer chromatic versatility without compromising geometric elegance. For contemporary approaches, grey-metallic NATO fabric emphasises the technical component of the quartz movement.

The Trésor 428.18.26.60.04.003 uses straight spring bars positioned at 12 and 6 o'clock. Using a small spring bar tool (extractor), gently push the bar from one side, lifting the opposite end, then withdraw the strap. Repeat symmetrically. Verify the new strap's lug width measures exactly 13mm to avoid lateral play. If inexperienced, consult Casati Milano atelier for professional strap change.

Any strap constructed with a 13mm lug width is compatible with the 428.18.26.60.04.003. Milano Straps offers ready-made straps in alligator leather, calf, shell cordovan and fabric, all featuring 13mm lugs and steel fittings. Bespoke straps can be commissioned from Casati Milano atelier, with personalised leather selection, thread colour and buckle choice.

A quality leather strap (alligator, calf or shell cordovan) typically lasts 3–5 years in daily use, with variation depending on climate, humidity and frequency of wear. Natural vegetable-tanned leather visibly ages, developing characteristic patina and creasing. Milano Straps provides an 18-month warranty on all bespoke straps from Casati Milano atelier, covering construction defects and material faults.
