Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Sedna Gold / Diamond / Wave Diamond / Bracelet

The Omega Aqua Terra reference 220.55.34.20.99.006 has a lug width of 16mm. This measurement is crucial for strap compatibility: measure from the inner shoulder to inner shoulder of the lugs and ensure you mount straps specifically sized for 16mm, not 14mm or 18mm, to avoid play or difficulty inserting the strap.

For the Aqua Terra 220.55.34.20.99.006 in Sedna Gold we recommend alligator in dark brown or cognac, which enhances the warmth of rose gold. Shell cordovan is an excellent alternative for softness and durability. Vegetable-tanned calf offers natural aged patina. Avoid light colors and cool tones (pure black, blue, green) that create discord with the warm metal.

Remove the old strap by placing the watch on a soft cloth. With a spring bar tool, gently press the internal bar of the lug to disengage it from the case slots. Extract the old strap. Insert the new strap by aligning the holes with the lugs, then press the bar until you hear the locking click. Repeat on the other side. Do not force: the fit should be natural at 16mm.

Yes, any artisanal strap with certified 16mm lug width is compatible with the Aqua Terra 220.55.34.20.99.006. Milano Straps offers custom collections for this width, customizable in leather (alligator, calf, cordovan), color, length and buckle type (rose gold or steel deployante). Always verify that the strap is specifically made for 16mm.

An artisanal strap in fine leather on this Omega lasts an average of 5-7 years of daily wear, depending on the leather. Alligator lasts longer thanks to its compact grain structure. Vegetable-tanned calf develops natural patina, gaining character but requiring more maintenance. Shell cordovan is extraordinarily resistant (8-10 years). Milano Straps guarantees 18 months of craftsmanship and offers regeneration and custom replacement services to extend your strap's life.
