DESCRIPTION
Watches — watch
Speedmaster '57 Green 40.5mm Leather Strap
Ceramic and steel in one case, under sapphire crystal — materials chosen for how they age rather than how they photograph.

Stainless Steel
Stainless steel gives the case the heft that tells your wrist there is something there.
Ceramic
Ceramic holds its colour and its gloss instead of fading into something dull.
Sapphire Crystal
Sapphire crystal means the view of the dial stays as sharp as the first afternoon.
Ceramic, steel, and the way things age
Ceramic is the material that keeps a surface looking exactly as it did, because it does not take on the dullness that softer finishes collect. Stainless steel handles the structural work, which is why the case feels solid rather than light in the hand. Sapphire crystal covers the dial, and it is the piece that decides whether a watch still looks cared for.

What a ceramic case says quietly
People do not describe a watch; they absorb it and adjust. The depth of a ceramic surface is the kind of detail that registers at close range, in a handshake or over a menu, and it makes the rest of what you are wearing read as chosen. The adjustment is small, and it is in your favour.
The bit between the lines
How it feels after a long evening
A ceramic surface stays cool and smooth under the fingers, and you will find your thumb going to it while you think.
What you get is not the compliment; it is the dozen seconds across a working morning where you look down and the thing is simply right.

Why it costs what it costs
We hold this stock ourselves and send it out from our own shelves. No boutique floor to pay for, nobody taking a cut in between — one step from our rack to your door instead of four. The piece is not cheaper; the route is shorter.
Store offer
Two pieces get you a cap. Three get you a cap and a wallet.
It runs across the whole store, so the pieces do not have to match.
- Any two items — a cap goes in the box, free.
- Any three or more — the cap plus a wallet.
Ceramic, and a short run
A batch this size does not sit around, and a restock is not guaranteed. Ceramic finishes shift between runs, so the next version is a near miss rather than a match.
