I ordered the Luminox Guardian Navy Seal limited edition watch. A nice looking watch and what l was looking for. However, in the website it clearly shows the anchor and palm tree illuminated. I asked First Class about who advise me to return the watch which l did. I cannot complain about the turn around service. Again, another however, l received the watch back and still the logo does not illuminate, unless you hold a torch over this for two minutes, then it illuminates for a small period of time. Everything else operates correctly. Not too happy with the watch now and considering returning it and requesting a refund unfortunately.

A great service and product in purchasing the new Luminox Guardian Watch. It took me a lot of deliberation over which one to buy. I’m really pleased l made the right decision in buying the Guardian, looks great on the wrist. However, a little over priced l feel, but time will tell.
