Service crystal or the no date model, where is the LEC located? is it one of the way to verify the authenticity of Rloex?
siodee,
On the service crystal, the LEC is at the 6 o'clock position, just that it may not be exact 6 o'clock. Some are and some are not. As for the no date model, not sure where it is located, some may be at the 6 o'clock position, some may not.
The LEC and ROLEX on the rehaut are just some of the ways Rolex are combating fake watches. The safest way to verify if the Rolex is original is to bring it to the RSC and ask them to check (but not 100% fool proof either, more so with vintage Rolex). Of course there are other things that you can do to check, like serial and model number between the lugs (older models), checking the serial number to known list of serial numbers (check the Internet), removing the case back to check the movement (correct to the model), checking the model number on the case back and year made (inside the case back) to the model number between the lugs and year made. General condition of the watch. Paperwork if any. BUY THE SELLER, not the watch.
And most important, if it is too good to be true....
