Strap for Seamaster Aqua Terra 150m Master Co-Axial 41.5 Yellow Gold / Champagne / Bracelet

The lug width of this model is 20 millimetres. This dimension is consistent across the Aqua Terra collection and is proportioned to the 41.50 mm case diameter. Be sure to measure correctly from shoulder to shoulder at the case base to verify compatibility with aftermarket straps.

High-quality alligator is the most aesthetically coherent choice, as the natural grain dialogues elegantly with the gold without competing. Vegetable-tanned calf in cognac or dark brown tones also offers excellent results. Shell cordovan maintains a rigid structure ideal for preserving the watch's proportions.

The Aqua Terra is equipped with standard straight lugs. Use a spring bar tool to gently remove the lugs from the opposite side, extracting the metal pins. Proceed slowly to avoid damage to the gold case. For risk-free replacement, Casati Milano offers strap replacement service by appointment.

Yes, provided it respects the 20 mm lug width with tolerance below one millimetre. High-quality straps from specialized suppliers are fully compatible. Ensure the strap is designed specifically for luxury watches, not generic sport instruments.

A high-quality alligator or shell cordovan strap lasts an average of 5-7 years with daily use, especially if protected from prolonged exposure to salt water. Vegetable tanning increases longevity. Casati Milano offers an 18-month warranty on all custom-made straps.
