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.
