Purpose-built diver for daily wear

The Steinhart OCEAN One 39 103-0981 is a 39 mm stainless steel watch rated to 30 ATM with a black ceramic bezel and flat sapphire glass. It runs on an automatic Swiss ETA 2824-2/SW 200 movement with 25 or 26 jewels and a second-stop function. The black dial carries Super-LumiNova BGW9 on hands and markers for low-light legibility.

Upgrade from fashion or entry-level divers

This model replaces quartz or basic automatic divers that lack a screw-down crown, ceramic bezel insert or 30 ATM rating. The jump is worth it when you need a true tool watch specification — 316 L case, applied luminous compound and a deployment clasp — without stepping into luxury pricing tiers.

Straightforward sizing and strap changes

The 20 mm lug width uses spring bars so bracelet swaps need only a basic tool. The 16 mm safety deployment clasp adjusts via micro-holes for fine fit. Common issues: the ceramic bezel can chip on hard impacts and the anti-reflective coating on the inner glass surface may show fingerprints more readily than untreated crystal.

Questions about this item

What lug width and spring-bar size does the 39 mm case require for a replacement strap?

The case uses 20 mm lugs with 20x16 mm spring bars, so any 20 mm strap with matching spring bars will fit.

How do I set the time and date on the ETA 2824-2/SW 200 movement without damaging the screw-down crown?

Unscrew the crown counter-clockwise until it pops free, pull to the first click for date (position 3), second click for time with second-stop, then push in and screw down firmly to restore 30 ATM water resistance.

When should the automatic movement be serviced and what seal needs checking to keep the 30 ATM rating?

Service every 3-5 years; the screw-down case back gasket and crown seals must be replaced during service to maintain 30 ATM water resistance.
