Frequently asked questions

What is the lug width of the Frederique Constant Carree FC-303MS4C26?

The lug width is precisely 22 mm. This specific dimension is determined by the proportions between the case diameter (30.70 mm) and the lateral attachment lugs. Accurate measurement is essential: use a digital calliper positioned perpendicular to the case at the strap insertion point to obtain the exact distance between the two lugs.

Which strap is recommended for the Carree FC-303MS4C26?

The Carree accommodates multiple options beautifully. Alligator in brown or black offers maximum versatility and formal elegance. Vegetable-tanned calf leather develops natural patina over time. Rubber or NATO fabrics provide contemporary functionality. Selection depends on context: alligator for formal occasions, natural calf for daily wear with aesthetic development, rubber for high-humidity environments.

How do I change the strap on a Frederique Constant Carree?

The process requires a spring bar tool. Position the watch on a stable surface, gently press the tool button to release the internal spring mechanism, remove the existing pin, insert the new strap into the upper lug, reinsert the pin and press until you feel a secure click. If uncertain, consult a professional: pressure must be controlled to avoid damage to the lug holes.

Can I use an aftermarket strap on a Frederique Constant Carree FC-303MS4C26?

Yes, provided the lug width is exactly 22 mm. Quality aftermarket straps—particularly alligator, calf and rubber—are fully compatible. Ensure your supplier explicitly specifies 22 mm to avoid fitment issues. Milano Straps provides a complete collection of 22 mm-compatible straps with customisation options and artisanal quality guarantee.

How long does a leather strap last on a Frederique Constant Carree?

Longevity depends on tanning method and usage patterns. Vegetable-tanned calf, worn daily under normal conditions, lasts 3-5 years before replacement. Alligator, being more durable, achieves 5-7 years of service. Deterioration accelerates if exposed to frequent perspiration, direct sunlight or constant humidity. Rotating between multiple straps significantly extends individual lifespan. Periodic maintenance with purpose-designed conditioners (not universal products) extends durability by up to 30%.
