16610M? Hmm?

[El Cascarrabias]

It's my understanding that the later 14060's (Submariner) had some subtle changes and the reference was designated 14060M.

What about the 16610 (Sub/date)? Did the latter models include any refinements? I've never heard of a 16610M.

The 14060 movement changed from the older simple balance cock type 3000 series to the newer balance bridge type 3130, and the M designation stands for “Modified”.

Did not know that!

AFAIK the 16610 came with the 3135 (same as the 3130 but with the date) movement from the start so wasn’t modified as such - hence why no 16610M.

A 16610 M, would only be referring to the serial #, and not have anything whatsoever to do with the 3135 movement!

So, the 3135 did not benefit from any modifications that were added to the 3130?

In what way would it refer to the serial number?

How does the 14060M refer to the serial number?

Just curious . . .

No, the 3135 movement in the Sub Date model 16610 (or any model containing a 3135 for that matter) did not have any reason to benefit from a modification that was made to an entirely different movement!

Please re-read my post, as I never indicated the M in a 14060M had anything to do with a serial #. However, as pointed out previously, the M on a 14060M stands for Modified...as Rolex made an improvement to the 14060 movement!

You will see many threads over the years though referring to an 16610 M (which have a 3135 movement),but again...that would only be referring to an M serial #, not the 3135 movement!

That said, around the 2008 time frame, you could have purchased an M serial # 14060M as well...which clearly is an 14060M movement on an M serial no date Sub!

No, no, no...…

The Rolex 3000 movement was Modified with a full balance bridge, larger balance and a couple of other minor changes.

All Oyster Perpetuals with the 3000 movement that got the Modified movement, re-numbered 3130, have the M stamped case.

That goes for Air Kings, OP's, and Subs.

I have always wondered why the non date sub starts with 14.. why not 16 like the rest of the tool range?

The refs with 16 all have a date. Refs with 14 don’t.

I thought the same but my 116500 disagrees with this.

There is a 16610T

It's not a 16610T. It is a 16610 and the T is a separate stamp.

The T (for Trou) is stamped on all cases that had pierced lug holes, then changed to the non-pierced lugs without releasing a new model.

You will find the T on most of the cases and models in the line until they changed model numbers, such as to the 116610. You must use the later modified bracelet end-links on the T stamped cases or you will not get your bracelet back off.

The 14060/M never got the non-pierced lugs so there are no 14060/M cases stamped with a T.

In terms of Submariners or non Chronograph sports.
