Hi, just so you know, that model actually has a Ronda movement, not ETA. TAG uses some Ronda movements although they previously were all ETA.
Personally I think the ETA chrono is a better model but it is more expensive and difficult to repair when there's a problem, and the coils do tend to go out. I thinkif TAG qualified the Rondas for their watches, even though they are cheaper they probably meet TAG's quality requirements!
I haven't seen this rep model in person so can't comment on the lume.
