The BERNY AM339MS is a 42 mm automatic dive watch on the Japanese Miyota 8215 movement, with a sapphire crystal, 20 bar water resistance and an internal rotating dive bezel turned by the upper crown. The lume is applied thick, and the orange first-15-minutes segment is easy to read underwater.
The internal bezel sits under the crystal, so it can't be knocked off its setting in the water. At 49.3 mm lug to lug it suits wrists from about 17 cm.

Questions
Can I dive with the BERNY AM339MS?
It is rated 20 bar and built as a dive watch, so it suits swimming and recreational diving with both crowns screwed down. Have the seals checked every couple of years if you dive with it regularly.
How does the BERNY AM339MS dive bezel work?
Unscrew the upper crown at 2 o'clock and turn it to line the orange triangle up with the minute hand; elapsed minutes then read off the ring.
