Well my twenty quid special has arrived. The nato doesn't have the omega logo on the buckle as per the photo, probably a good thing, but is nice enough quality, and seat belt material, worth half my outlay roughly.
The case is solid stainless with an o-ring groove and o-ring behind the case back, and a screw down crown which also has an o-ring. Neither of which means its waterproof of course, but they are there at least. Machining and finish is pretty good for the cost.
The crystal is flat with a cyclops and appears to be sapphire, but this I cant verify.
Lume isn't bad, nicely applied to the indices. Hands and dial nice quality, again allowing for the price.
The bezel is unidirectional without a great action, but I've come across far far worse. The insert is high gloss and etched not printed, not bad at all.
The movement is a generic Chinese Mingzhu, a slight disappointment but again, at the price what the heck. It has handwind and hacking aswell as being automatic.
£20.09! Not bad at all, but I wouldn't have been so happy if I'd paid the sixty and upwards they ask via buy it now. An Amphibia or Seiko 5 would be a far better bet, both in quality and far cooler.
