The Seiko Alpinist has long ranked as one of the best entry-level mechanical watches on the market, and it’s not hard to see why. Its combination of tool watch specs with a surprisingly elegant design that makes it easy to wear anywhere, plus its approachable price, has made it popular among enthusiasts and first-time collectors alike.

To round off 2025, Seiko has updated the Prospex Land Alpinist line, with this eighth-generation model improving upon its specs and durability even further while also adding some stylistic flair and making it truer to its roots.

Its a touch more expensive, but it is also notably half a millimetre thinner than the previous generation and now utilises a Diasheild coating - a clear ceramic PVD layer that vastly improves the case's scratch-resistance. Is it a fair trade off? Watch Jamie's full hands-on review of this new eighth-generation of Seiko Prospex Land Alpinist watches and find out.
