The Seiko SNR029 is a diver watch from the Prospex collection, part of the LX line family. It has a 44.8 mm titanium case, 15.7 mm thick, 50.9 mm from lug to lug.

Who it suits

  • Wrists of roughly 18.0–19.9 cm (7.1–7.8 in), by our Watch Finder sizing guide
  • Swimming, snorkelling and diving

Strengths

  • Sapphire crystal resists scratches
  • 300 m water resistance
  • Screw-down crown helps keep water out
  • 72 h power reserve survives a weekend off the wrist
  • Spring Drive: a smooth-gliding seconds hand and high accuracy

Trade-offs

  • Thick at 15.7 mm: harder to slide under a cuff
  • Long 50.9 mm lug-to-lug can overhang smaller wrists
