Frequently asked questions

Can you fit a standard strap on the Omega Aqua Terra 2503.34.00?

No, the bracelet is integrated directly into the case: the attachments are not proprietary but specific to this model. A standard strap will not fit. This is why I created the <a href="/pages/casati-booking">Casati Milano</a> service, where I craft the strap by hand directly on your watch, respecting the original architecture.

How does the custom strap service work for the Aqua Terra?

We work by appointment only at <a href="/pages/casati-booking">Casati Milano</a>, Via XX Settembre 15 in Milan. I take measurements directly from the case, study the attachments down to the millimetre, and create the strap with tailored craftsmanship. Every piece is built for the watch you own, not the other way around.

Which leather do you recommend for this model?

I prefer Tuscan leather in hazelnut: it speaks naturally to the warm tones of the teak dial and keeps that sporty-elegant character of the Aqua Terra. If you love patina, honey Barenia develops in a way that only time can create—extraordinary ageing.

How long does a well-made strap last?

With ordinary wear and a little care, 5–7 years easily. The leather breathes, adapts to your wrist, and ages with dignity. It doesn't fade: it becomes more characterful. Simple maintenance—avoid prolonged water exposure, let it breathe—extends the life even further.

Why was the Aqua Terra created in this form back in 2002?

Omega intended to build something urban and everyday that carried the maritime legacy of the Seamaster without the deep-dive robustness. The teak dial and 150 metres of water resistance say it all: it's an elegant tool that doesn't fear the sea, but lives in the city. A rare balance that I've learned to respect in every strap I make.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
