Is the SRPL13 worth it over a cheaper Seiko diver?

Yes if you want 200m diver's rating, an automatic movement and the Samurai case. Cheaper Seiko 5 models skip the diver's rating and use less robust cases.

How does it compare with the SRPD/SRPE Samurai models?

The core Samurai case, 4R35 movement and 200m rating carry over. Differences are mostly dial, bezel and finish, so pick on looks and price rather than capability.

What is the power reserve and accuracy?

About 41 hours on a full wind. Seiko rates the 4R35 loosely, so expect a few seconds to tens of seconds a day of drift rather than chronometer accuracy.

Will it fit a small wrist?

The 41.7mm diameter is moderate, but the 49.5mm lug-to-lug is long and the watch weighs 170g. Under about 6.5-inch wrists it will overhang and feel top-heavy.

Can I put it on a different strap?

Yes. It uses 20mm lugs, so most 20mm straps fit. A NATO or rubber strap cuts weight noticeably.

What comes in the box?

The watch on its stainless steel bracelet, plus Seiko's manual and warranty card. No extra strap or tool is typically included.

Our take on the SEIKO Prospex Samurai Automatic Black Dial Men's Watch SRPL13

The Seiko Prospex Samurai SRPL13 is an automatic dive watch with a 41.7mm stainless steel case, 200m diver's water resistance and Seiko's 4R35 movement with about 41 hours of power reserve. Its angular Samurai case, black dial and Hardlex crystal keep it a rugged everyday diver at a relatively accessible price. The 49.5mm lug-to-lug and 170g weight make it feel substantial on the wrist. It is a mainstream Prospex model, so street pricing tends to sit well below Seiko's list and moves with promotions rather than collector scarcity.
