Omega Seamaster Planet Ocean 600M diver

The Omega Seamaster Planet Ocean 215.30.44.21.01.002 is a stainless steel automatic watch rated for 600-meter water resistance. It features a black analog dial with index markers at 12, 6, and 9 o'clock. A helium-escape valve and rotating bezel support professional dive timing. The deployment clasp secures the bracelet during active use.

Sustained pressure and salt-water exposure

The 600-meter rating and screw-in crown maintain seal integrity during prolonged immersion. The helium-escape valve releases trapped gas during decompression stops, protecting the sapphire crystal. Stainless steel construction resists corrosion from repeated salt-water contact. Automatic movement continues running without battery changes while at depth.

Verify wrist fit and service access

Confirm the round case profile suits your wrist dimensions before ordering. Ensure a local watchmaker can service the automatic movement and pressure-test the helium-escape valve after battery or seal work. Check that the deployment clasp adjustment range matches your strap-length preference. The date display advances via crown position, so familiarise yourself with the setting sequence.

Questions about this item

Does the 600 m helium-escape valve affect daily wear comfort or heat on the wrist?

The helium-escape valve is a passive safety feature for saturation diving; it adds no active heat, noise or power draw during normal all-day wear.

What strap or bracelet must I already own to use the 215.30.44.21.01.002 deployment clasp?

The watch ships with its integrated stainless steel bracelet and deployment clasp fitted, so no separate strap is required for it to function.

Will the screw-in crown and 12, 6, 9 index layout work with my vintage NATO straps?

The screw-in crown and fixed lug bars are designed for the supplied bracelet; vintage NATO straps would not engage the deployment clasp or maintain 600 m water resistance.
