I got the 38mm for the wife. I love the fact that it's quartz since she doesn't wear them often enough and they stop, which forces me to re-set them.
As to her 38mm, it's a really nice piece. It's made me want to pick up a 44mm for myself.
Link ?
Yes the gen is quartz and has no date.
There are 2 levels of reps, make your choice wisely : some have an ETA quartz, some a Ronda Quartz (cheaper). They look very similar but often the cheap ones have a date, which is wrong.
The gold/blue movement is definitely ETA.
I just received that EXACT same watch from Lay for my wife. I also have 2 44.5mm Big Bangs myself and the 38 mm is quite small. Not sure if you would like it because the strap is quite thin. Wears very well as a women's watch.
As far as I know, the genuine IS Quartz BUT only comes with the diamond bezel and no plain SS bezel for the 38 mm size.
I've tried on a gen 41mm Big Bang and I would say that is a nice size if the 44.5 mm is too big for you. Fits like a 40mm Rolex sports model. As far as I know , there is no quality 41mm Big Bang Replica.
