Seller-Listed 20Bar / 200m Water Resistance
Seller Specification: 20Bar = 200 Meters
The supplied specification screenshots classify the watch for diving and state a water-resistance depth of 20Bar. The detailed specification separately states 20Bar = 200 meters.
The watch also uses a screw-down crown and screw-down case back, both relevant to maintaining the case sealing system.
A pressure rating does not guarantee safe use at the stated depth under every real-world condition. Crown position, seals, age, impact, servicing and temperature can affect water resistance.

Watch Care & Maintenance
- Make sure the screw-down crown is completely secured before exposing the watch to water.
- Do not unscrew or operate the crown while the watch is submerged or wet.
- Avoid strong impacts even though the seller lists the watch as shock resistant.
- Keep an automatic mechanical movement away from strong magnetic fields whenever practical.
- After exposure to saltwater, rinse the exterior with fresh water when appropriate and dry thoroughly.
- Avoid saunas, steam rooms and rapid extreme temperature changes because heat can affect watch seals.
- Clean the steel bracelet and sapphire crystal with a soft, non-abrasive cloth.
- Periodic professional servicing may be required depending on usage and movement condition.
Important Specification Notes
41.5mm case vs. 40–44mm field: the product title identifies this model specifically as 41.5mm, while the generic AliExpress specification field states 40 to 44mm. Both seller values are preserved separately.
Movement variation: the seller lists both Miyota 8215 and Miyota 8315. The product screenshot currently shows Miyota 8215 as the selected variation. The movement actually supplied depends on the option chosen when ordering.
Band width: AliExpress displays a generic band-width field of 20 to 24mm. The corresponding SN0036-G model specification identifies a specific width of 20mm.
Water resistance: the seller states both 20Bar and 20Bar = 200 meters. This is a seller pressure rating rather than a guarantee of safe operation at every real-world depth.
Diver terminology: the listing calls this a diver/diving watch, but the supplied screenshots do not show an independent ISO dive-watch certification. No ISO certification is claimed in this description.
Color variations: Enamel Blue, Enamel Black and Enamel Green are listed. Photos and appearance can therefore differ according to the selected variation.
