Rolex Movement

[LuminousMaximus]

On the latest Rolex Sub c 116613LB and GMTii 116713LN, and Sea Dweller, do they all utilize the same movement?

And if not, Are there ones that would keep the time better than others? The reason I asked is that one person said after 55 days his Sub C only lost 1/4 of a second! That's pretty impressive to me...

GMTs and Subs use different movements. Regulation can vary widely between watches, even of the same model.

Whats even more impressive is that he can measure a 1/4 second!

The 116613 & 16600 Sea Dweller use the same movement which is the cal. 3135.. The 116713LN has a cal.3186 GMT Movement. They all use a base, which all three are the same base movements which is cal.3135.

Have to agree and sounds to me someone living on fantasy island,and will add most Rolex use the cal 3135 and its clones.Now basically these movements have changed very little since 1988 when it was introduced.Now we have most new models with the in-house made escapement parts,but it all come down to how well any movement has been regulated.As today no purely mechanical watch will keep 100% perfect time any brand and any price but most Rolex out of the box are 99.994% accurate or slightly more.
