A league of their own-
Larry did an excellent review in this older thread, and when doing research on shock and water depth resistance of the Submariner references-It had to take.

The 10 sub-heading attributes are excellent and pretty much correct.
About number 1 and #4):

However, in Paul Altieri's " Last of the Best" 2018 historical tech article on the 14060-14060 M Submariner references, the 14060 had the 3000 caliber WITHOUT a Breguet overcoil hairspring and did NOT have a full balanced bridge. This was corrected with the 14060M, indicating modified-3130 caliber- with inclusion of both these reliable accuracy features. In 2007, Rolex decided to add the COSC designation with a 4-line dial chronometer movement.

For those who really follow the evolution of the Rolex Submariner, Altieri's article
on the 14060/14060M "Last of the Best" article is required reading.
I certainly agree with his line of reasoning on the lug holed, Triplock-Breguet hair springed -full balance bridge deep diving 14060M Submariner.
It may just be the last of the best.

I like the colors of the 3135/3130 cal movements. Especially
the Breguet overcoil spring, larger balance wheel, and full balance bridge.
Even the white COSC lettering color....

All the colors have a professionally engineered " Rolex Design" tint to them.


Its kinda tool watch warm to resurrect a pertinent older thread...........

Cool. As an engineer I appreciate the details.

In addition to the excellent durable virtues of Rolex engineering, particularly the tool watches- there is timeless value. The current Submariners will last as long as their vintage cousins, and some of the vintage watches give 50 years of service like the 5513 and 1680 references.
Few other watches give 50 years of service, then have appreciated in value
better than blue chip stocks. So, keeping the slightly faster newer watches serviced is a good investment in current reliable use, and future eventual value. Rolex watches seldom go down in price over time. Maybe you can know the correct time while wearing a hedge against inflation.

Yes -- broken movements.

Are you kidding me, watch designers? A watch that can be damaged so easily?
We know the "high end" expensive brands that feature this stupidity.

Jeesh! And for that reason alone I would never own that type of archaic movement "technology".

{Just my humble opinion; others' views may vary.}

They cite this as proof that "their" movement is as good as another, and then say they have a better clasp, so that their watch is overall "better". Or they say that their clear case back shows some nice designs and evidence of superior workmanship,(we're not sure superior to what) therefore it is "better".

This shows no understanding in what makes the watch tick....

So.........let's talk about what makes a Rolex movement actually better, from an engineering perspective, than others..

1. All Rolex movements have a full balance bridge. This adds stability and superior support to the balance which is the brains of your movement. Many others do not.

2. Rolex uses screw locks to hold the movement in the case...no clips, no bend tabs...solid mounting.. it won't move around in the case.

3. Free sprung balance. This allows free movement of the hairspring and it is not attached, or anchored to a regulator screw, but rather the balance wheel is timed by actually adjusting the inertia of the wheel (balance screws, kind of like balancing your car wheels) itself rather than just adjusting the length of the spring

4. Breguet over-coil hairspring. This is known to help the watch keep more consistent time as the mainspring unwinds so the watch is accurate over a broader range of power from the traditional flat-spring used in other makes.

5. 31 jeweled movements as a standard so jewels are at all wear points rather than 23, 25, or 27 as found in many other high end watches.

6. 10mm balance wheels. More mass equals more stability and more consistent operation during use. It is much more difficult to disturb the heavier mass of a Rolex balance wheel than it is on the typical 9mm balance wheel of other watches.

7. Teflon coated reverser wheels for smooth and quiet, lifetime operation.

8. A removable and easy to disassemble reverser module for easy cleaning rather than a fixed and riveted module as used in some others.

9. Rolex uses additional gearing to run the center seconds which results in a slightly thicker movement, but one that is stronger and more stable.

10. Cam, jewel, and spring actuation of the date change function. This allows you to change the date in a Rolex at any time, without issue, because the date change function is disassociated from the hand stack gears. Many other movements will be broken if you change the date between 9pm and 3am. It also snaps the date over instantaneously.

I'll stop here before you fall asleep....

But I will say.............This is why my Rolex is better than your XXXXX watch..
Then what is missing, if anything, in an in-house Tudor movement?
