My First Rolex: Explorer II Polar 16570....Plus a few Questions!

[logantrky]

Two days ago I purchased a pre-owned Rolex Explorer II with polar dial (16570) from a very reputable pre-owned seller. This happens to be my first Rolex and I'm still in disbelief that it is on my wrist!

I have lusted after a Rollie for years and it has finally become a reality!



It is a "T" serial number (1995?) and I believe it has a Tritium dial (I believe) with the Swiss-T<25 inscription.



Now on to a couple questions...

1. It seems to run flawlessly and hasn't lost or gained a second in the past two days. I do not have record of the service history, however. I have read on the forums that a routine service should be performed every 5 years. Should I send it away soon to Rolex for a service or wait until I notice a change in the way the watch performs?

2. It may be difficult to tell from the photo, but the hour markers have a very nice patina. The dealer offered to swap the dial for a new one since the lume has stopped working. I WOULD like to get the lume back, but I'm not sure that it would be a wise move considering I may lose the original dial. Thoughts?

Thanks for your input! :)
