What reviewers say
SRPL15 Prospex Samurai Diver 41.7mm
Owners praise the Samurai's bold design, comfortable fit, and reliable Seiko automatic movement. The black coating is a divisive feature, with some loving the stealth look and others worrying about long-term wear.
- Striking blacked-out appearance
- Comfortable on the wrist despite 49.5mm lug-to-lug
- Accurate timekeeping for the price
- Hardlex crystal can scratch
- Black coating may chip over time
- Strap quality could be better
Invicta Men's 18508 Pro Diver Gold Dial Yellow Gold Steel Bracelet Automatic Dive Watch
Pro Diver automatics are generally liked as value buys: owners report the Sellita keeps good time and the watch feels heavier than its price. Common complaints are plating wear, a thick case and weak resale.
Questions and answers
- Which is better for actual diving?
- The Seiko. Its 200m rating is stated as suitable for scuba diving, and it has a screw-down crown and a lighter case. The Invicta is also rated 200m but is aimed more at casual wear.
- Which movement is better, the 4R35 or the Sellita SW200?
- The Sellita SW200 is Swiss made and generally considered a step up in finishing and accuracy. The Seiko 4R35 is a proven, easy-to-service workhorse with about 41 hours of power reserve.
- Which wears smaller?
- The Invicta is 40mm wide versus 41.7mm for the Seiko, but it is 14mm thick versus 12.3mm. The Seiko's 49.5mm lug-to-lug makes it feel larger on the wrist.
- Which lasts longer?
- Both are mechanical and need servicing every few years. The Seiko's Hardlex and the Invicta's flame fusion both scratch; neither has sapphire. The Invicta's gold plating can wear off with daily use.
- Is the Invicta worth buying over the Seiko?
- Only if you want the gold-tone look and the Swiss movement. The Seiko offers a lighter case, a dive-rated 200m rating and stronger owner ratings.
