Strap for Conquest Quartz 25 Ceramic

The lug width (misura ansa) of the Longines Conquest L3.157.4.57.6 is precisely 12mm. This dimension is characteristic of the feminine models within the Conquest family and is considerably rarer than standard lug widths such as 14mm, 16mm, or 18mm. To verify this measurement, insert a calliper between the case lugs: the distance must be exactly 12mm. A strap with an incorrect lug width will not seat properly and will create visual misalignments with the case.

The ideal material depends on your intended use and desired aesthetic. For a formal appearance, we recommend alligator in black or vegetable-tanned calf leather in deep tones (black, seal brown, burgundy). For a sportier approach, silicone or rubber straps maintain comfort during warm seasons. NATO straps in Ballistic or quality synthetic materials offer chromatic versatility. The ceramic bezel of the Conquest should not compete with the strap: choose materials with regular surface texture and subtle grain that harmonise with the minimalist design of the case.

Changing the strap requires a dedicated tool: a spring bar tool. Locate the lateral pins that hold the strap attached to the case. Insert the flat end of the tool into the slot beneath the pin, apply gentle upward pressure to compress the spring, then remove the old strap. Repeat on the other side. Insert the new strap, aligning the pins with the case slots, and ensure the strap is fully seated. Verify that there is no lateral movement: the strap must not shift beyond the case margins. If you are uncertain, consult a professional watchmaker or the Casati Milano atelier.

On milanostraps.it you will find a curated selection of straps manufactured for the 12mm lug width, ready for dispatch. The available models range from classic alligator to vegetable-tanned calf, from sporty rubber to synthetic textiles. Each strap can be personalised in length (to fit your wrist), with embroidered initials and choice of stitching thread. For a broader selection or a fully bespoke solution, the Casati Milano atelier creates custom-made straps with personal selection of leathers and updates via WhatsApp during production.

The lifespan of a leather strap depends on usage patterns, climate conditions, and leather quality. A high-quality alligator or vegetable-tanned calf strap typically lasts 3-5 years with daily wear. Straps exposed to high humidity, chlorine, or saltwater will deteriorate more rapidly. The patina that develops over time is not a defect but a desirable characteristic: each strap tells its own wearing history. To extend the life of your strap, store it in a dry location, avoid direct impacts, and clean it periodically with a soft cloth. Bespoke straps from Casati Milano benefit from an 18-month guarantee against manufacturing defects.
