I use it in a medical hyperbaric chamber so haven't got it wet yet, but it keeps great time and is not to heavy. It appears to be well made and has a solid feel to it which I like. The luminosity is great and its easy to ready at night especially if its been in a bright place during the day. It claims to be 1000m waterproof I cant comment on that but I would be comfortable and will be recreational and tech diving with it , ### ⭐⭐⭐⭐⭐ Solid build quality *by on Reviewed in the United Kingdom 19 September 2025* Excellent,,solid build quality,perfect size ,keeps perfect,,,illumination on dials is superb at night ....very impressed,,,for the money as well ,superb ### ⭐⭐⭐⭐ Tough watch. Not perfect. Good value. Poor lume. Great time *by on Reviewed in the United Kingdom 30 November 2025* £130 just about right. I has the mark 2 version (not sure what the difference is). Good points- watch feels well built (in an industrial way). I wear it as everyday wear and it a big ‘man’s watch’ that you don’t have to worry about. Sapphire crystal looks good and despite previous reviews. I have found the time keeping on mine excellent. Not so excellent is the lume. Which strangely. Is championed in other reviews?!. Lyme strays off bright and faded very, very quickly. I appreciate it’s not going to be seiko or citizen standard, but is not as good as the Chinese watches I have either. The rubber dtrap is in keeping with the watch, however the little things that the strap tucks in to broke very easily. I had to replace them with some from a different watch I have. All in all. You get what you pay for. Worth the money if you’re going to wear it everyday. It’s a real friend on your wrist, that will stick with you through anything. Like all friends- it’s not perfect. Comfy watch for its size. ## Frequently Bought Together - RATIO FreeDiver Helium-Safe Dive Watch Sapphire Crystal Automatic Diver Watch 1000M Water Resistant Diving Watch for Men - Gute Automatic Watch for Men, Mens Skeleton Automatic Mechanical Wrist Watch Analog Casual Sport Brown Leather Clock, ‎ 24 x 2 x 1.4 cm, strap --- ## 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.tn/products/640464113-freediver-helium-safe-dive-watch-sapphire-crystal-automatic-diver-watch](https://www.desertcart.tn/products/640464113-freediver-helium-safe-dive-watch-sapphire-crystal-automatic-diver-watch) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-18*
