Strap for Conquest Classic Automatic 29.5 Stainless Steel / Red Gold / MOP / Strap

The lug width (measuring ansa) of the Longines Conquest Classic L2.285.5.88.3 is 20mm. This measurement refers to the distance between the two lugs of the case where the strap attaches. It is a standard width shared by many women's and unisex models of small to medium size, allowing access to a vast range of compatible aftermarket straps.

For the Conquest Classic L2.285.5.88.3, the ideal strap is alligator in warm tones (cognac, burgundy) or neutral shades (black, dark brown), as it enhances the rose gold-steel two-tone without weighing down the design. Vegetable-tanned calf leather is a versatile and elegant alternative, developing a patina over time. For less formal looks, pearl-grey NATO offers practicality whilst maintaining sophistication. Shell cordovan represents the premium choice for those seeking a strap that ages beautifully.

To change the strap, use a dedicated spring bar tool or consult a professional watchmaker. Position the tool in the opening at the base of the case, apply gentle pressure to release the internal spring of the lug (spring bar), then carefully remove the old strap. Insert the new strap by aligning both lugs in their respective slots and verify that the spring is correctly positioned. A bespoke atelier such as Casati Milano offers this service complimentary with bespoke straps.

The lifespan of a leather strap depends on material quality, frequency of wear and maintenance. A high-quality alligator or shell cordovan strap can last 5–10 years or longer, developing a fascinating patina over time. Vegetable-tanned calf has an average lifespan of 3–5 years, with notable colour evolution. To maximise longevity, avoid prolonged exposure to water, direct sunlight and store the strap in a dry environment. Bespoke straps from Casati Milano include an 18-month warranty against manufacturing defects.
