LONGINES Hydro Conquest L3.647.4.56.6 Unidirectional Rotating Bezel, Black Watch, calendar, and bezel operation are all normal. It has been used to a certain extent, but it has been handled with care, so it is in good condition for an older model. There are minor scratches on the bezel that are difficult to convey in the images. It has not been used underwater. I feel that it is a highly accurate quartz watch, close to the annual rate level. Movement: Quartz Water resistance: 300M Crystal: Sapphire crystal, no noticeable scratches Case size: Approximately 39mm (excluding the crown) Lug width: 19mm Bracelet: Full links if extra links are added Accessories: Everything shown in the images.
