Very solid watch rated to an incredible depth of 200M. Has an adjustable diver's bezel so you can track how long you've been underwater or use for other timing purposes. Has date function. The crown screws shut to make it water tight, so to adjust time you unscrew the crown counter clockwise until it is out a little, then you pull it out to set date/time as a regular watch. Once set, you push the crown in and screw shut so it is water tight again. If you've never had a watch with crown like that, it's good to know why it doesn't just pull out to set the time, and to know what you need to do afterwards so that you don't leave it unscrewed and go swimming. Keeps great time/date. Band has some dirt in the threads area and could be cleaned to lighten. Really nice timepiece. Ships USPS first class or priority mail.
