Datejust Purple

A watch built around a genuine Seiko movement, with aftermarket parts for the case, dial, hands and bracelet. We choose every combination, so you get a look you won't find on the shelf.

No. ModHouse isn't affiliated with Seiko or any other watch brand. We use genuine Seiko movements because they're reliable and any watchmaker can service them.

Not on automatic models (NH34, NH35, NH36, NH38, NH70, NH72). They wind themselves as you wear them and keep running for about 41 hours off the wrist. If yours stops, wind the crown 20 to 30 turns or simply wear it.

Some chronograph models use Seiko VK mecha-quartz movements, which run on a battery. The movement is listed on every product page.

Most models are 39 to 40 mm. Some are also offered in 36 mm, which suits slimmer wrists or a vintage look. The case size is in the specifications of each watch.

Bracelets adjust from about 14.5 to 22 cm. Every box includes a link removal tool, so you can size it at home in a couple of minutes. Any jeweller can do it too.

Most models are rated 3 ATM: fine for rain and washing your hands, not for swimming or showering. The water resistance of each model is in its specifications.
