Awesome transaction...great product. Ordered a watch from 1saleaday and have to say it is really nice at what was a fantastic price. I own omegas, tags, raymond weils, oris', epos', and more...bought over many years at great prices... and I have to say, this $100 Philip watch may now be my favorite. I ordered an inexpensive italian rubber band off of Amazon and subbed it out with the nice (real) croc that comes with the watch so I can use it for everyday knock around. All I can say is wow. Even my wife liked the watch and was wondering whether it might "fit" her. I quickly told her no and found an excuse to get it back. Now to the main issue, I was initially concerned whether the watch had a sapphire or not. I emailed customer support and they responded a day later with what appeared a conscientious and responsive answer. They had already received a couple of emails and went back to the manufacturer, more than once, and they confirmed that a sapphire was put on this particular model. They also pointed me to a large competitor's online video where it was cited as sapphire. Ironically, the competitor's video clearly cited a sapphire but the online text said mineral. Anyhow, it certainly appears a sapphire, at least by the water droplet test which may or may not be conclusive but which seems to work in most cases. I'm not willing to try a screwdriver scratch but I'm reasonably sure it is sapphire and I was very pleased with the customer support. By the way, I received the watch five days after ordering which by my standards is pretty darn quick. All in all, a very nice transaction. Would definitely purchase from them again.
