Review: Outstanding Watch, Shipping and Price - Love love love this watch! It is gorgeous. The sapphire crystal, the cathedral hands, the cyclops calendar, the green dial, the gold numerals, the super shiny bezel and lugs are all outstanding. The brown leather watch band is very secure with a locking closure and two tips at the front and the back of the bracelet for extra security. I have a very small wrist and this fit very well. This watch is only 1.5 mm larger than my Bulova field watch but does not look bigger. It, however, is more prominent on my wrist because of its height. The band fits much better than any other watch manufacture band. I read complaints about the band but with exception of the color, I don't wear much brown, I love it. The shipping was fast. I received it a day early. It was a great price for a great watch. Thank you Wristoutlet.
Review: Absolute banger of a watch - Beautiful! Not as big and bulky as it looks in the pictures. Looks sporty and versatile with lots of class, and goes well with a ton of different bands. Get compliments all the time
