Maybe a silly question, but does it tell the actual time and is there a stopwatch and alarm too?** A: The timer has various countdown and standard timer features such as stopwatch and tells the time. At the the end of a countdown it can be set to start counting up as well. Mine doesn’t have an alarm but the countdown has quite loud audible beeps at the marker points. For all the features, search the internet for the instructions, they are out there. **Q: Does it have a backlight for use at night?** A: I apologize for the delay. unfortunately not! **Q: what is the width of the watch strap please? 20mm?** A: The srap on the Optimum Time Big Sailing watch is 30mm wide. **Q: can I set loop reminders at set times ? how many reminders can I set? is this waterproof IP68?** A: 30mm ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly recommended! *by B***L on 14 August 2014* Highly recommended!

We took it to the world championships in Italy and it didn’t work. Such a nightmare and now too late to return now we’re home. So having to buy a new one. Hopefully this one will work. ## Frequently Bought Together - Optimum Time Series 3 Sailing Watch in Yellow - Water Resistant Race Timer for Sailing - Optimist Racing: A Manual for sailors, parents & coaches (Sail to Win) - Schaefer Little Hawk MK1 Wind Indicator f/Dinghies Up to 6M --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/48920285-series-3-sailing-watch-in-yellow-water-resistant-race-timer](https://www.desertcart.us/products/48920285-series-3-sailing-watch-in-yellow-water-resistant-race-timer) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-23*
