What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Sternglas Marus

The Sternglas Marus is widely praised for its well-built, heavy feel and excellent bezel action, considered the best in its price range. Despite its 42mm diameter and 52mm lug-to-lug, owners report it fits surprisingly well on slim wrists. A reviewer notes the short seconds hand as a drawback, but highlights the watch as a fun, affordable starting point for a collection, featuring a vibrant Pepsi bezel and an anthracite dial that shifts in appearance, powered by a Miyota 8215 movement for €399. Overall, owners and reviewers rate the Sternglas Marus highly for its robust build and superior bezel at its price point.

Smiths NATO PRS-40 AUTOMATIC

Smiths NATO PRS-40 AUTOMATIC owners praise its rugged, futuristic, and unique design, with some describing it as "badass" and others finding it an acquired taste with 70s or "Gattaca" influences. The watch is noted for its smooth-winding Seiko 6R15 movement and is considered "bombproof" for harsh environments, making it a suitable "beater/grab and go" option. While the purchase process can be difficult due to limited stock, one owner reported quick delivery. The 12 o'clock crown position is seen as unique and easy to use by rolling. On balance, owners appreciate the Smiths NATO PRS-40 AUTOMATIC for its distinctive, robust design and reliable movement at its price point.
