Strap for Constellation Quadra Quartz 28 Chronograph Stainless Steel / Diamond / MOP/ Alligator

The Omega Constellation 1847.73.31 is fitted with an 18mm lug width. This measurement is standard for 28mm ladies' Constellation models and is the correct reference when searching for a compatible strap. To verify compatibility, measure the distance between the case lugs: a handcrafted strap will have a width slightly less than 18mm to ensure smooth passage through the attachments without forcing.

It depends on your use and the finish of the case. For a formal wrist presence and a patina that ages beautifully, a vegetable-tanned calf leather in cognac or hazelnut enhances stainless steel. For those who appreciate tactile luxury, black <a href="/pages/termine-glossario/alligatore">alligator</a> leather conveys an uncompromising presence. If you seek everyday versatility, a NATO strap in canvas or linen allows infinite color combinations while maintaining the collection's rigour. For durability, vegetable rubber is ideal if the model is destined for elegant sports contexts.

The Omega Constellation 1847.73.31 uses standard spring bars for 28mm ladies' watches. You will need: a strap change tool (even improvised with a thin flat blade), a stable and well-lit surface. Position the watch with the case side facing upward, locate the spring bar beneath the lug, depress it slightly downward, and slide the lug out of the pins. By reversing the process, insert the new strap, ensuring the springs engage perfectly. Avoid abrupt movements that could damage the crystal or case.

Yes, any strap with an <a href="/pages/termine-glossario/misura-ansa">18mm lug width</a> is compatible. Handcrafted straps from Milano Straps, such as those offered in the <a href="https://milanostraps.it/collections/cinturini-orologi-per-misura-ansa-18mm">18mm strap</a> catalogue, are fully compatible with this reference. The build quality of a bespoke strap, in noble leather or shell cordovan, transforms the wearing experience far more than any aesthetic variation of the case itself. Some models also offer a personalized <a href="/pages/termine-glossario/deployante">deployante clasp</a>, which adds security and comfort.

A quality calf leather strap, with vegetable or synthetic tanning, has an average lifespan of 3-5 years with daily wear. Longevity is influenced by ambient humidity, cleaning frequency, direct sun exposure, and type of perspiration. <a href="/pages/termine-glossario/alligatore">Alligator</a> and <a href="/pages/termine-glossario/shell-cordovan">shell cordovan</a> offer superior longevity (5-8 years), thanks to the fibrous density of the leather. The 18-month warranty offered by Casati Milano for bespoke straps covers manufacturing defects and ensures priority replacement if useful life is compromised by manufacturing faults, not by natural wear.
