+1 on the variations of lume...
Personally the only one I have had in my hand that I rate above the rest is the 288...
Given its always worth getting any new movement serviced and I always would its no bigger effort to get the lume redone and CP... given the CP shape can also be seen easily in certain light reflections..
As an aside... I was chatting with a guy I didnt know, who was wearing a latest version A7753 250 the other day..... I have to say the lume was a real give away when he held it out to show me, I think he knew I had spotted it as rep because he pulled it away sharply and tucked it under his jumper nonchalantly after that and stopped moving his arm about... I reckon it was one of the second versions which had the poorer lume and silvered subdial hands...
Funnily enough the other thing that really caught my eye was the rep alligator strap.... the sandwich edging really seemed obvious compared to the turned edge of the gen...... First time I had seen one on somebody elses wrist...
and no I didnt call him out...
