Frequently Asked Questions
Movement options, early bird savings, specifications and ownership questions.
Is the OCT-0030 a no-date watch?
Yes. Both the ST2130 and Sellita SW200-1 versions feature a no-date dial.

The ST2130 is a Chinese automatic movement, while the Sellita SW200-1 is Swiss-made. The watch has the same external design and specifications with either option.
Why does the Sellita version cost $110 more?
The price difference comes from the choice of automatic movement. The case, dial, bezel, bracelet and 200m water-resistance rating remain the same.

What is the water-resistance rating?
The OCT-0030 is rated to 200 meters (20 ATM). Always ensure the crown is fully screwed down before exposure to water, and have the seals tested after opening or servicing the watch.
Can I use the rotating bezel to time a dive?

What kind of crystal is fitted?
The watch uses sapphire crystal with double-sided anti-reflective coating and an anti-fingerprint treatment.
What type of lume does it use?
Swiss BGW9 luminous material is applied to the hands and hour markers, providing a blue glow in the dark after exposure to light.

The 316L stainless-steel bracelet is 21mm at the lugs and tapers to 16mm at the folding clasp.
How do I care for the automatic movement?
If the watch has stopped after not being worn, wind it gently using the crown before wearing. Avoid setting or winding the watch while the crown is screwed down, and secure the crown afterward.
