Questions about this item

How deep does the 300M water-resistance rating actually let me take this watch?

The 300M rating means the watch is tested for pressures equivalent to 300 metres depth, making it suitable for serious recreational diving and professional marine activity.

What lug width and strap system does the 40.00 mm case use for the synthetic band?

The 40.00 mm stainless-steel case is fitted with a synthetic strap secured by standard spring bars; the lug width matches the band supplied by the manufacturer.

How do I wind and set the automatic movement correctly after the watch has stopped?

Unscrew the crown, wind clockwise about 30 turns to build reserve, pull the crown to the date position to set the date, then to the time position to set the time, and finally push and screw the crown down fully to restore water resistance.
