How to chk for M series?

[pingpong]

Hi,

current production series is M. one key sign of M series is the ROLEX Chapter Ring (except for the SD), however I believe some late Z series also have the ROLEX Chapter Ring. Explorer II also have this ROLEX Chapter Ring rite?

any other way to chk on the M series? the warranty card? if yes, what is written to show that it is M?

Thanks

The serial number will be MXXXXXX on the warrenty card. It's inscribed on the chapter ring if there is or if not it is in between the lugs.

best and sure way is to check on warranty card and cross check inbetween the lugs at the 6o'clock position.

alternatively if you do have the CRB you can just check at the 6oclock position too.
