Review: 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 ,
Review: Great watch - Why did you choose this product over others?: I like the look of this watch,and it keeps very good time,also the day and date are easy to read and there a illuminated markers for the hours.

Why did you choose this product over others?: I like the look of this watch,and it keeps very good time,also the day and date are easy to read and there a illuminated markers for the hours.

### ⭐⭐⭐⭐ Really a 4.5 rating
*by N***R on 27 January 2026*

Ok.... this is a very good watch...It keeps very good time, assuming you wear it for at least 8 hours a day. I also give it a good 30 second "shake" before bed.... I find it comfortable to wear and not very heavy (on line it says it weighs a pound... I weighed it and find it closer to a little over a half pound) I had a Seiko dive watch when I was 21 and SCUBA diving.. This watch comes close to that performance level. It keeps good time, is comfortable and seem to be well built... The reason I gave it 4 (4.5) stars is the setup of date, time, etc... is that the stem is a little "sensative" or tricky to set... Once set, it works... I just found it a tricky to setup. I included a picture of me wearing the watch... I am 70 years old, 6 foot and about 215 pounds. I wear the watch on the inside of my wrist based on how I was taught to wear a watch when I was diving. The band seems to be wide enough to accommodate a bigger wrist than mine.
