Is there a 'high torque' drop-in alternative to the Miyota Super2035?

Hi all.

Does anyone know of a 'high torque' drop-in replacement for a Miyota Super 2035?  

I am attempting a 'hydro-mod' of a watch which is powered by the Miyota, but to give myself the best chance of success, I'd like to use a stronger movement to counteract the 50cst Silicon oil I will be using.

I have in my box of bits a Ronda 503 which supposedly a high-torque movement, however it is a different size and shape.  Most of the problems I could overcome (dial feet placement, retaining ring, seconds hand, etc), but the Ronda has a different stem depth (terminology?  depth from surface of movement to centre of stem.  1.1mm for the Miyota vs. 1.5mm for the Ronda).  So before I go hacking into the Ronda, I am wondering if there are any known 6 3/4”’ x 8”’ movement I might try?  I have looked but found it hard to ascertain the 'torque' of many movements - it doesn't seem to be a common differentiator.

Many thanks in advance.

Many thanks for that - very useful.  From what I am reading it seems that the Super2035 is in Miyota's "Power Engine" range - meaning that it is already a high torque movement.  Interesting...

Yes, it's going to be my nod to a Ressence!  I have some vintage military watches in my collection.  One of the things that really appeals to me in the fact that the combination of a (black) dial set high in the case and a domed acrylic crystal gives the effect of the dial almost being painted inside the crystal - and a very good viewing angle.  I have a 1980 CWC G10 'Fatboy' which exhibits that effect, and recently discovered some cheap Chinese copies of the CWC that will make excellent victims for my oil-filled modding experiment 🙂

Just to round this off... I did the hydro-mod on the cheapo G10 copy.  All went well, the seconds hand is ticking away nicely although how long the battery lasts remains to be seen.  I used a strip of closed-cell neoprene foam which may or may not provide a little compensation for thermal expansion/contraction - we'll see!  Here it is with its venerable grandfather.

      Nice interesting diver Razz, i have a sheffield dress watch, different movement altogether. Could be a wrong motion works part, how does the setting feel before fitting the cannon pinion, clutch and intermediate wheel meshing ok ?  The less traditional setting design could be suspect, the second wheel has a slip clutch assembly, that most likely needs looking at. LA is 42 ° Razz Tbh i  much prefer to call the complete unit the lever, then use the seperate names for all of its components. Such as guard pin, fork, fork horns, fork slot, lever arm, pallets , pallet arms, pallet slot, pallet stones. I suppose pallet fork is the combination of the two opposite ends that make up the lever, its also called the anchor which is descriptive of its appearance.  Its a pretty basic 1930s  swiss lever movement H and yes Nev was meaning the pallet fork.

      The pallet fork should really be called a lever, English lever, Swiss lever etc but most people including myself call it a pallet fork.

      Seiko have case numbers, I  can't see it on your photos.  If you can find that we can look for a genuine crown.  If not, you need to measure the diameter of the stem, the distance between the lugs and the depth of the lugs.  The case number will be something like this.

      I'm not sure what kind of movement this is, but I'm curious to know if you're using the word "lever" as a synonym for "pallet fork"?

      Actually kind of rough, maybe munute wheel pinion problems? Is the 2.73mm canion oinion which seems rarer and not availble on Cousins UK. The seconds hand works and suprising nice amplitude but don't know the lift angle and BE this one says 17 j but is a pin pallet as well. Cap jewels on the escape and drive train pivots. Interestingly in has both water proof and shock resistant on the caseback and dial. Puts this around 1969 or '70? The double bezel that works independently is cool has the pi symbol on each. Wonder if it can be used like a slide rule ir something...
