Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Sedna Gold / Diamond / MOP / Alligator

The Omega Aqua Terra 220.58.38.20.55.001 features a 19 millimeter lug width. This measurement is the internal space between the two spring bars that support the strap. You can verify it easily with a digital caliper gently inserted between the pins. If you desire a custom strap, always communicate this measurement to the manufacturer.

For the 220.58.38.20.55.001 in Sedna Gold we recommend three main options. Vegetable-tanned alligator leather (cognac brown or burgundy) enhances the rosy tone of the gold and offers timeless elegance. Vegetable-tanned calf leather is more versatile and durable, perfect for everyday wear. For sports contexts, a NATO strap in cotton or hemp in neutral tones transforms the character of the watch. Each choice creates a different aesthetic: match the material to your lifestyle.

To change the strap you will need a spring bar tool and a flat surface. Rest the watch with the case facing upward, gently insert the tool's lever between the lug and the strap, and push downward to compress the internal pin. The strap will detach easily. To install the new one, align the lug holes with the pins and press until you feel the click. Work carefully to avoid scratching the Sedna Gold case.

Yes, but with caution. Many Omega watches and other brands feature 19 millimeter lugs, however it is essential to also verify the lug-to-lug distance (the length of the lug from pin to pin), as this may vary. The 220.58.38.20.55.001 has a specific lug-to-lug distance. Before purchasing an aftermarket strap, always communicate the exact reference of your watch to the manufacturer to avoid incompatibility.

A premium handcrafted leather strap (alligator, shell cordovan or vegetable-tanned calf) typically lasts 3 to 5 years with daily wear, provided proper care is maintained. Constant exposure to moisture, perspiration and UV rays accelerates aging. Suggestions: remove the watch before sleeping, avoid prolonged fresh water exposure (the Sedna Gold resists up to 150m, the strap does not), and occasionally apply a hydrophobic cream specific for watch leather. The patina that forms is desirable and characteristic; replace the strap when elasticity declines significantly.
