great watch so far :)
What a bargain ! great looking dive watch with helium valve . 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 ,

Tough watch. Not perfect. Good value. Poor lume. Great time
£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.

Looks great
Looks like a great watch and it's heavy, but returned it without using as I didn't know my wife had already purchased me a Tag Heuer watch.

Good Ratio!
Ratio of quality to price: Designed by Italians, soli Seiko movement. Sturdy divers watch, Safire glass. Company? Singapore? So, what? That’s life now. Anything beautifully designed, is eventually produced in Asia.

…runs slow 🙄
Beautiful looking watch with very good luminosity but unfortunately the timekeeping is poor and it loses about two minutes a day so I wouldn’t really recommend this unless you’re happy to reset the time each day
