Collector photographs

Taken by people who own this reference: their light, their wear, their patina. Not the maker’s photography. Where the maker hasn’t given us a photograph, one of these is shown as the main image above, always credited. A few are the Atlas’s own, and say so.

No collector photographs yet

If this watch is in your collection, yours would be the first. A photograph on the wrist shows what a studio image cannot: scale, wear, and how the piece has actually aged.

How to get one

The maker's page for this exact reference, the same page this catalogue's specifications are sourced from.

Direct from Airain

Airain publishes its current collection and its retailer or service network on its own site. Start there for what is actually in production; this catalogue records references whether or not they are still sold.

Buyer’s tip

Check the reference number against the maker's own page before buying anywhere else. It is the one detail that is hard to fake and easy to verify, and it is what the specifications on this page are keyed to.
