Sellita SW200-1 Operation


Please read the below guides to minimise risk of damaging the movement.

Crown positions:
1: Winding
2: Date setting
3: Time setting


Take a look at the back of your new watch and you’ll see the stunning SW200 movement on full display through the exhibition case back.  

The beauty of an automatic movement, is that it’s self-winding. Meaning that the oscillating weight winds the mainspring with the movement of your wrist. So, as long as you’re wearing your watch, it will stay wound (and for up to 41 hours after thanks to the power reserve). The movement can also be manually wound by unscrewing the crown into position 1 before turning clockwise. 

Note: Remember you’re dealing with really small gears here so avoid excess force and speed when operating the crown for any function.

1) Unscrew the crown (anti-clockwise) and gently pull out to the time setting position (position 3).
2) Turn the crown until the watch reads the appropriate time
3) Push the crown back in and turn clock-wise until firmly in place (be careful not to over-tighten the crown as this can damage the movement) 

It is recommended to always turn the hands clockwise to minimise long term wear to the movement.

Note: Remember you’re dealing with really small gears here so avoid excess force and speed when operating the crown for any function. 


The window at the 3 o’clock position displays the date, which will change as the watch hands pass midnight.

The Sub-Aquatic also has a quick set date function:

Quick-Set Date

Before using the quick set date function, make certain that the watch is displaying a time between 4am and 8pm.
This avoids movement damage by ensuring that the automatic date changer is not engaged.
(To avoid confusion, it is recommended to ensure the hour hand is in the 6 o’clock position) 

With the watch time set appropriately, unscrew and pull the crown into position 2. Then, gently turn the crown clockwise to roll the date forward. Once complete, push and screw in the crown to reseal the watch.

The date cannot be rolled backwards in manual or quick set functions. An attempt to do so may damage the movement.

Note: Remember you’re dealing with really small gears here so avoid excess force and speed when operating the crown for any function. 


The Sub-Aquatic is fitted with a 120 click, uni-directional bezel with lumed ceramic insert.
Whether you're timing a dive or timing your steaks on the grill, simply rotate the bezel so the zero matches the current minute hand. As time passes, the minute hand will then point to the elapsed time on the bezel. 

Note: The bezel is designed to turn anti-clockwise only.

  • Black Ceramic Bezel of the Pompeak Sub-Aquatic Swiss Powered Dive Watch


Switch the lights off and your new watch really starts to shine thanks to the use of BGW9 Swiss Super-LumiNova throughout the dial and bezel. Looking fantastic and extending readability throughout the darkness. 

This lume is charged by light, so the more rays the lume is exposed to, the brighter and longer it will glow for.

The matching 904L stainless steel bracelet with it’s brushed outer links and polished centre links is a beauty. These links are ‘screw in’ and can be removed and replaced easily with a small flathead screwdriver.

Note: Repeated movement can cause screws to work loose. For this reason, we recommend checking and re-tightening on a regular basis. 

The bracelet also features a sliding micro adjustment buckle. This feature is great for adjusting around a wetsuit, or just loosening on a hot summers day.

Here’s a quick video to show the function:


The Sub-Aquatic is available with high end rubber straps, complete with quick release pins for easy strap switching without the need for any tools.
To use, simply push the pin towards the centre of the strap and gently remove. 


What use is a dive watch without water resistance?
The Sub-Aquatic is sealed to 20ATM/200m which makes it more than capable of recreational diving. 

In order to complete the seal, ensure the crown is fully screwed in before contact with water.
All seals around the crown, case back and glass must be correctly seated and in good condition. 
Ensure all moisture is removed from the watch prior to operating the crown.


We pride ourselves on creating the watches we want to wear, from the aesthetics to the materials used, and as such, our watches are designed to turn heads and built to last.

There are however always thing’s you can do to keep your automatic watch working as smoothly as possible:

Wind off the wrist

Should you need to wind the watch, it’s best to take it off your wrist first. This minimises any potential strain on the stem (it’s also much easier to wind with two hands).

Keeping moisture out

Moisture, along with dust is a movement’s nemesis. It can easily damage the delicate internals of the mechanical work of art.
With up to 200m water resistance, this shouldn't be an issue, provided all seals are closed.

Should you take this watch around water or in a particularly humid environment, be sure to keep the crown firmly screwed down at all times, and ensure all moisture is removed before you unscrew it again to wind or set the time.

Shock and magnets

Whilst the movements are built to resist the effects of both shock and magnetic fields, large sudden shocks may knock the gear train out of sync. Prolonged exposure to strong magnetic fields will also reduce the accuracy of a movement. This falls under general care, but it’s always good practice to look after your watch, no matter how durable.


Just like the mechanics on a car, in order to keep the movement running as smoothly as possible, we recommend that your service your timepiece every 3-5 years. This will include checking, cleaning and oiling of mechanical parts along with checking and replacing gaskets to maintain the water resistance, and can be completed by your local service/repair centre.

If you notice a watches movement behaving oddly, it's best to visit a service/repairs shop right away.

If you need help here, please do get in touch.


With no batteries in sight, a mechanical watch is one of the most reliable tools you’ll own.
Take care of it correctly and it’ll last for generations.

To ensure you get off on the right foot, your new timepiece comes with 2 years warranty.
If you have any problems at all, please do get in touch via our website.
