I opened up my SD43 and noticed that on the newer 3235 movement, Rolex has gone back to using case clamp tabs to hold the movement in the case.
Anyone know why they didnt use the same movement removal method of tightening the screw to loosen the movement in the case that previous movements used? Seems odd that they would go back to older ways.
Could it be because the SD43 case is too big for the movement?

Looks like there's a lot of extra room in there, period. They can't use screws alone with that much space. Cutting the case closer to the movement would weigh more, otherwise I have no explanation myself.

Very interesting - thanks for sharing

eonflux · 15 September 2020, 03:42 AM

Interesting.
Thanks for posting.

The 3235 and 3135 movements are the same diameter.
So a larger case with more empty space inside wouldn't be unexpected if that extra space isn't filled in by case material.

Smobews · 15 September 2020, 05:25 AM

Is there some kind of spacer between the movement and inner case?

Crazy how ugly looking and industrial Rolex movements are ... Glad can’t see
It

Calatrava r · 15 September 2020, 05:34 AM

And those tabs can break loose if the watch is dropped and then the movement is loose in the case. Were the screws more secure and robust?

32 series are the modernized version of the 31 series. Redone in the age of CAD with improved tolerances and manufacturing technics. I hope you are kidding with your no doubt comment.

TriaXenginE · 21 November 2020, 02:10 PM

The cal 3135 mounting seems more secure since the movement had to be turned to the cutouts in order to release it. The movement tabs look out of place in the 3235 especially since the previous model just looked more integrated in execution.

Jocke · 21 November 2020, 04:57 PM

The reason is there must be some space for the helium gas.

ThatSubGuy · 21 November 2020, 06:58 PM

Still better than the plastic holder inside a $3k TAG Hauer, lol. Oh yeah, the entire movement is only held in place by the crown.

shedlock2000 · 14 January 2022, 05:07 AM

That’s very interesting. One of the things I liked about Rolex was the use of cam clamps (for want of a better term). It’s interesting they have used these tabs on the SD.

When you say ‘gone back to’ did they use the tabs in earlier watches? I’ve always been a gnt guy, so my experience only extends as far back as the 1675 — which I think used the cam-clamps?

And that is the reason I got rid of my Aquaracer yrs ago!

asiparks · 14 January 2022, 05:43 AM

Nothing wrong with a nylon or plastic spacer ring that supports the movement in the case for the entirety of it's circumference & height .

Funny

Laszlo · 14 January 2022, 06:35 AM

Interesting for sure - kind of makes me think, that watch is going for (gray) $17K (unworn), and you see this, and wonder, why? -- is it really worth it? Hell yes.

BMWMotoRider · 14 January 2022, 06:50 AM

No wonder Rolex doesn’t use sapphire backs. Not much to look at.

Nav01L · 14 January 2022, 07:22 AM

Could it be to allow the watch to “breathe” as it is compressed at great depth? Obviously there would be lots of pressure on the crystal at 4000 ft under water, this would push in the gaskets, the rehaut and might exert pressure on the dial and movement assembly that’s just better contained by giving all of this some room to move? Not sure this is more than a lose theory on my part, but wouldn’t be entirely implausible.

KY.. · 14 January 2022, 07:40 AM

Oh yeah, the good old days of off the shelf ETA movements in pricey watches.
