Strap for Clear Vision Automatic Rose Gold / Brown

The lug width of the FC-303C6B4 is 23mm. This is the internal distance between the two attachment pins located at the sides of the case. To verify, position a digital calliper between the pins and record the measurement in millimetres. Accurate measurement ensures full compatibility with aftermarket straps from our 23mm collection.

The ideal strap depends on usage. For formal occasions, we recommend black or cognac alligator with stainless steel deployante: the natural texture of exotic leather pairs elegance effortlessly with the 43mm case. For everyday wear, vegetable-tanned calf leather in black or brown offers versatility and develops a personal patina over time. For sporting or humid environments, moulded rubber ensures absolute durability and water-resistance.

The FC-303C6B4 uses a standard system with two spring bars that secure the strap to the case. Obtain a strap removal tool or a small pointed pin. Position it toward one of the side lugs and gently push the pin inward to release the spring. Extract the pin from the hole and remove the worn strap. Insert the new 23mm strap, align the holes with the lugs, and press the pin until it locks into place. Repeat on the opposite lug.

All straps with a 23mm lug width are compatible with the FC-303C6B4. Always verify the measurement before purchase: a width of 22mm or 24mm would result in unwanted play or installation impossibility. Our 23mm Milano Straps are produced bespoke and offer artisanal finishes in alligator, calf leather, shell cordovan, canvas and rubber, all with customisable deployantes or standard buckles.

Durability varies according to material, use and maintenance. A vegetable-tanned calf strap lasts approximately 3–5 years with daily wear, developing a patina that increases aesthetic appeal. Alligator, being more resistant, reaches 5–7 years of regular use. Moulded rubber lasts 4–6 years. Critical factors: avoid prolonged exposure to direct sunlight, fresh or salt water (except rubber), perspiration and excessive pressure. Keep the strap dry and store it away from heat sources. Proper maintenance significantly extends useful life.
