The 3035 is almost identical to the 3135 in size and basic composition…..

The 3135 movement picked up a full balance bridge, larger balance wheel and went from 27 to 31 jewels.. It’s basically just an evolution… Much like it will be when they all get fitted with the Parachrom hairspring and the Paraflex shock system…. Identical again, except for the new parts…

Padi56 on TRF makes an interesting note about the hairsprings:

…And the hairspring in the 3035 is glued on to the balance cock stud now they are laser welded on 3135.

Hi are the straps interchangeable between the GMT Master II. 16710 and the 11670? I like the new strap on the 11670.

HAd no idea the 3135 was made in 1988. They haven’t changed it after all these years. Still the best movement for a standard watch.

Thanks! But in actual usage did the accuracy and/or ruggedness of the movement improve considerably in the 3135?

Isn’t the Cal. 3035 COSC-certified?

Apparently the 3035 is not COSC certified, but my 1986 Date is accurate, even if it’s not, to within 1 second a day..

I have similar experiences with my Datejusts. I tend to think COSC is a marketing gimmick and I would like to hear watchmakers chime in on that thought. Being COSC or not doesn’t change the parts of the movement, it just means it was thoroughly regulated and passed the testing needed to qualify for the Chronometer label. The companies actually have to pay for that testing too.

I have seen non COSC cal. 3035 and COSC versions. Did you know they actually have non-COSC 3135 also? More commonly though is I think this post: 3035 non-COSC and 3135 COSC.

Laser welded on means the balance and hairpspring comes already attached from Rolex?
