Strap for Heritage Bicompax Annual Hometown Edition Basel

The lug width (ansa width) of this reference is exactly 18mm. This measurement is critical when selecting a strap: a strap must respect this specification precisely to ensure proper fit and correct optical proportions. To verify compatibility, measure the internal space between the two lugs with a digital calliper: the strap must fit without forcing and without lateral play.

For this timepiece we recommend noble vegetable-tanned materials: alligator with medium grain, split leather, or Japanese shell cordovan emphasise the formal elegance of the case. Ideal colours are dark cognac with natural patina, deep black for formal occasions, or cream for a minimalist effect. Grey-taupe FKM rubber remains a contemporary alternative if you seek versatility. Avoid NATO straps if you wish to maintain the stylistic coherence of the Heritage.

Remove the watch from your wrist and place it on a soft cloth, dial-side down. Locate the pins securing the strap to the lugs (one per side). Use a spring bar tool (a thin lever instrument, available from watchmakers) to gently press the internal spring of the pin, sliding it laterally. Once the pin is extracted, the old strap will be free. Insert the new strap through the lugs and carefully reinsert the pins, ensuring they are fully engaged.

Yes, any strap with an 18mm lug width is compatible. Artisanal Milan-made straps guarantee superior construction quality compared to generic aftermarket options: carefully selected leather, noble tannages (vegetable, Hermès), hand-finished details, and certified longevity. An artisanal 18mm strap of excellence completely transforms the tactile and aesthetic experience of the watch, enhancing its austere elegance.

Durability depends on the quality of the tannage and usage patterns. A vegetable-tanned leather strap, worn daily, offers 3-5 years of use before showing significant signs of wear. Japanese shell cordovan, being more robust, can exceed 7-8 years. Natural patination is desirable: leather darkens and develops a rich patina, a symbol of authenticity. To extend longevity, avoid prolonged exposure to moisture, fresh water, and aggressive detergents. Periodic maintenance with specialist creams every 6-12 months maintains suppleness and prevents structural drying.
