Our take on the Seestern S434-2 Professional Diver Automatic 200m Watch

The Seestern S434-2 is a 200m automatic dive watch built around the Seiko NH35 movement, a workhorse caliber with hacking, hand-winding and about 40 hours of power reserve. It uses a 316L stainless steel case and bracelet, a scratch-resistant sapphire crystal and a sunburst dial. Its only recorded price is $192 at the one store tracked, as of October 30, 2026, so there is no cheaper or higher point to compare against yet.

Questions and answers

Is the Seestern S434-2 worth it at $192?
At $192 it is a low-cost way to get a 200m automatic diver with sapphire and an NH35. That is competitive for a steel-bracelet microbrand diver, though the only recorded price is $192 as of October 30, 2026, so there is no lower point to wait for.
How accurate is the Seiko NH35 movement?
Seiko rates the NH35 within roughly -20 to +40 seconds a day. Real-world examples often do better, but expect to reset the time every few days.
Can I swim or dive with it?
Yes. It is rated to 200m, which covers swimming, snorkeling and recreational scuba. Have the crown screwed down and the seals checked before diving.
How long does it run without wearing it?
About 40 hours of power reserve. If you leave it off longer than that, wind it by hand through the crown to restart it.
What is in the box?
The watch on its 316L stainless steel bracelet. Box contents and included tools are not confirmed, so check with the seller before ordering.
How does it compare with a Seiko SKX or SRPD?
It offers the same NH35 family of movement and 200m rating, plus sapphire crystal, which the SKX lacks. The trade-off is a pin buckle clasp instead of a diver's clasp and less brand history.
