If you want to cut this watch's height by a trivial 1.3 to 2.3 millimeters, and short of changing to the slimmer ETA 2892 design movement, you will lose the technologically beautiful high specification IWC type soft iron dial and movement cage that is engineered into this model to make it much less vulnerable to magnetism. As mechanical watches lacking this feature are apparently fairly commonly magnetized and the consistency and accuracy of their timing rate sent more or less haywire by common sources of magnetism in the household and elsewhere, and by more exotic and aggressive sources of magnetism in some professional pursuits, etc., the high specification soft iron dial and movement cage is what makes this particular watch stand out, in my eyes at least, from the ubiquitously available and overwelmingly vast number of low technical specification dive watches designed predominantly around often very nice superficial cosmetic effect and otherwise cheap-easy-fast manufacture in more ways than one.
To my view there can be a huge difference between a good watch that looks good and a watch that just looks good, so I personally hope any future incarnation of the PRS-14 retains its beautiful high spec antimagnetic mov't cage and improves on its past self by incorporation of the original 1960s SM300's Mark XI type internally secured screw-down crystal design using a heavy and coarsely threaded steel retaining ring* and updated with crystal material respective interchangeable CTE** correlated temperature compensating metal washers that would allow the interchange of sapphire and acrylic or polycarbonate crystals in the same watch; a screwed-in crown tube meeting the now generic and ubiquitously available Rolex Triplelock specifications(assuming there are no legal problems involved in that at this point) to guarantee replacement part and gasketing supply; Speedbird 3 bracelet style removeable screw-cap solid lugbar pins; a nicely and discreetly incorporated date window; Sinn U2 EZM5 style DIAL/MOVEMENT PLATE ATTACHED twin desiccant capsule case moisture absorbing technology IF ---IF --- such is no longer legally protected by patent rights or any other standing legal protections of any kind; upgraded lume glow duration with the rumoured newly developed SuperLuminova "24Hour" type lume if such ever becomes available; materially upgraded water resistance sealing with high spec Viton type gasketing; reengineered caselugs so that the watch sits a bit better and more comfortably on the wrist; an optionally available Timefactors heavy-duty open end-link type Omega style mesh bracelet with a redundantly secure simultaneous push activated release opposing twin tab lock-up with auxiliary flip-up security hood lock dive type clasp; a standard production ETA specification movement of Swiss origin(or a Chinese origin ETA specification cloned duplicative counterpart if it's absolutely necessary), with a full on Swiss origin ETA chronometer grade/NO-COSC paperwork version of the same movement available on special order at extra cost and wait time.
I put all of the above ideas in a long post at the first page of this thread if anybody is interested. However, since writing that, and while prefacing this with the fact that I have a near personal revulsion of things made in Red China at the same time I am trying to be realistic, the idea put up that I really like and personally thought excellent was the one Luso had above of using the easily available Chinese ETA 2892 specification clone movement that Bob(RFrazier) tested(see TZ-UK "Classic Posts" subforum here) for the production movement with the full-on Swiss ETA 2892 chronometer grade version of the same movement available on an optional pre-paid special order extra cost/extra wait-time basis. Even if the special order option of the Swiss origin(?) ETA 2892 chronometer mov't was not workable or not available for Eddie, any individual owner dissatisfied with the Chinese ETA 2892 clone mov't in the stock watch would have the option of sourcing the higher grade Swiss mov't on his own for what I assume should be, due the supposedly exactly correlating mov't specifications, a drop-in fit and straight across exchange requiring only proper installation, regulation, and adjustment of the new movement.
One might consider that the Rolex OysterCase watches which started in the 1920s and reached their apex between the end of WWII and the end of the 1970s, became what they are in the mind of the popular culture of the world because they were technologically the best watches of their day while looking the part and not because they were watches that looked good and were comfy on the wrist alone. I personally think Rolex no longer really holds to what they were before the 1980s, but that is no denigration of the, I think, genuinely outstanding and well balanced contemporary engineering they once put into their watches in a wholistic sense so that these watches could better meet any extreme of use required. If that is forgotten or degraded much in designing or redesigning a tool watch, then I personally think it's just a fashion watch whatever its price is or whatever it pretends to be.
