Review: Race officer,s dream watch - This is a dream watch it not only works as a normal watch,but it's a brilliant race officer and sailor watch,I can't fault it 👏 Review: Utterly Useless When Wet - I'm going to start with the positives. The pre-programmed countdown function works really well, the moulded rubbery strap isn't the worst in the world and not uncomfortable, but has the potential to break off once its aged a bit... However, it'll never age because the watch will give up long before the strap decides it can't cope anymore. As the title suggests, this watch is useless when it gets wet, a bit of a problem for a watch advertised as a sailing watch. If you never plan on going afloat, but need a watch with a decent display and countdown function, then you'll be fine; however, at the first sign of a wave, the screen fogged up and some of the digits stopped displaying. After two days of careful drying out, the fog cleared to leave no digits displaying at all. It was dead. I have given this 1 star, as I simply couldn't give any less. This is a hopeless watch for those who sail on water. It may be better suited to radio sailors or land-yachters, but if you plan on actually getting wet buy a Casio or Timex instead, you're money will be much better spent! ## Features - Waterproof - Alarm - Water-repellent ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00H3L3N76 | | Age range | Adult | | Batteries | 1 Lithium Metal batteries required. | | Batteries included? | No | | Brand | Optimum Time | | Color | White | | Customer Reviews | 3.4 3.4 out of 5 stars (56) | | Date First Available | 4 Dec. 2013 | | Department | Unisex | | Display type | Digital | | Features | Alarm, Water-repellent, Waterproof | | Included components | Stainless Steel Buckle, Soft-touch PU Strap, Electro-luminescent Backlight | | Is discontinued by manufacturer | No | | Item model number | OS1120 | | Manufacturer | Optimum Time | | Package Dimensions | 10.4 x 7.6 x 6.6 cm; 120 g | | Power source | Battery Powered | | Shape | Tonneau | | Size | standard size | | Sport | Running | | Style | Strap | ## Images ![Sailing Watch OS11 Sailing Watch - Image 1](https://m.media-amazon.com/images/I/61DIha-cB3L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Race officer,s dream watch *by D***I on 5 September 2021* This is a dream watch it not only works as a normal watch,but it's a brilliant race officer and sailor watch,I can't fault it 👏 ### ⭐ Utterly Useless When Wet *by R***R on 23 August 2013* I'm going to start with the positives.

One of the push buttons fell off and the watch took on water.
