RATIOFreeDiver Professional Dive Watch Sapphire Crystal Automatic Diver Watch 500M Water Resistant Diving Watch for Men

Well made works as it should, Ratio is well worth a look if you are after a watch ..this is better than other well known brands

Great watch, metal, either with leather, and silicone straps. This is by far the most comfortable in the water or out. The only criticism is the manual it's ambiguous regarding helium release valve on this model.
