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.

Spinnaker Bradner Pearl Diver

The Spinnaker Bradner Pearl Diver is noted by owners as large on smaller wrists, with a 50mm lug-to-lug and 15mm height being a concern, though some find it acceptable with specific strap choices. Opinions on finishing quality vary, with one owner reporting issues like a poorly seated bezel and crooked indices. Overall, owners rate the Spinnaker Bradner Pearl Diver with mixed reviews regarding its size and finishing.
