Frequently asked questions
What is the correct lug width for the Omega Aqua Terra 231.50.42.22.06.001?
The lug width for the 231.50.42.22.06.001 model is 20mm. This width is specific to the 41.50mm case and is the standard compatibility specification for all aftermarket straps for this watch. Measure the distance between the attachment pins to verify correct compatibility before purchase.
What strap do you recommend for the Omega Aqua Terra in red gold?
For an Omega Aqua Terra in Red Gold, we recommend straps in alligator, cordovan, or vegetable-tanned calf leather. Alligator and cordovan create a naturally luminous dialogue with the warmth of red gold; vegetable-tanned leather offers more understated versatility. All our 20mm straps are compatible and customizable for the 231.50.42.22.06.001.
How do you change the strap on an Omega Aqua Terra?
The strap is secured via spring bars inserted into the case pins. Use a dedicated tool or lever to gently press the pin from one side, partially extracting it. Slide off the old strap, align the new strap's spring bar with the hole, and release the pin. Verify that the spring bar is fully secured on both sides before wearing the watch.
Is a 20mm aftermarket strap compatible with my 231.50.42.22.06.001?
Yes, all straps with a 20mm lug width are compatible with the 231.50.42.22.06.001. The width must correspond exactly to the distance between the case pins. Our straps are specifically tested for this model and available in multiple materials: leather, rubber, NATO fabric.
How long does a natural leather strap last on a daily-wear watch?
A quality leather strap with vegetable tanning or alligator leather lasts an average of 3-5 years with daily wear, varying according to climate, humidity, and maintenance. Naturally dyed leather develops patina over time. We recommend alternating straps to distribute wear and protecting leather from prolonged water exposure. Our straps include an 18-month warranty from production.
