Strap for Constellation Master Chronometer 39 Sedna / Blue / Alligator

The lug width of the Constellation 131.53.39.20.03.001 is 24 millimetres. This measurement is precise and is essential for compatibility with aftermarket straps. You can verify it by measuring the internal distance from shoulder to shoulder of the lug itself, or by measuring the width of the base of the original strap.

For the Constellation in Sedna Gold we recommend black alligator for maximum formality, or vegetable-tanned calf in cognac colour if you desire a leather that evolves over time, creating harmony with the natural patina of Sedna Gold. Bourbon-coloured shell cordovan is ideal for those seeking chromatic depth and versatility.

The strap is changed by removing the lug bars that connect the strap to the case. You will need a specific tool (lug bar remover) to push the lug bars safely without scratching the gold case. If you prefer, many experts offer this service. Remember that the new strap must be exactly 24mm wide.

Yes, a 24mm strap is compatible with any watch that has 24mm lug width. However, the strap length may vary depending on the proportions of the case. Before purchasing, verify both the lug width and the total length required for your wrist.

A leather strap constructed with premium materials and vegetable tanning typically lasts 3-5 years with daily use, provided it is maintained correctly. The leather must dry completely if exposed to moisture, and it is advisable to avoid prolonged contact with water. The standard warranty is 18 months, and many craftspeople offer leather replacement or repair services.
