Never owned or serviced one. Are they efficient with the autowinding when serviced? I am curious as normally the auto,s have a large rotor I presume because a heaver rotor, rotates more efficiently than a light rotor.

Hi CB.

There is a lot of information on the net that well describes the pR os and cons of these movements better than I could.

What I will say is when wearing one on a daily basis I could not personally tell the difference between a micro rotor and an ordinary rotor, apart from the thickness of the watch. Mine both work fine, and when left overnight enough power reserve to be put back on my wrist without extra winding.

I have read somewhere that in some of the higher end incarnations of these movements the question of winding efficiency with the smaller rotor is addressed by making it out of pure gold to increase its mass. This has also been done in some of the top end full rotor autos though, and there are quite a lot of expensive M/R autos without gold rotors, so either the impact was too low to justify the cost, or it was just another marketing gimmick along the lines of the jewel count.

      Need some crystal replacement advice

      By VWatchie · Posted

      I just picked up this Mondaine quartz watch on tradera.com for £11. It's a non-runner so I will replace the Ronda movement (£10.95 at Cousins), polish the case, replace the case-back gasket, and replace the mineral crystal. Now, the problem is finding a suitable crystal. The original crystal is slightly domed (2.4mm thick dome), measures 36.4mm in diameter, and is 1.3mm thick at the edge. The closest I can get on CousinsUK is 36.5mm in diameter, 3.1mm thick dome, and 1.5mm thick at the edge. I think the replacement crystal would look OK, but the problem is finding a suitable glass gasket. The case diameter for the glass gasket is 36.9mm and the closest glass gasket I can find on CousinsUK is either 36.8x36.0mm or 37.0x36.2mm. I guess one of those glass gaskets could work but as you can see there's no way the 36.5mm domed crystal would fit the inner diameters of those glass gaskets. I guess I will have to give up on a domed crystal, no? So, the backup plan is to use a (1.5mm) thick flat mineral crystal as the diameters come in increments of 0.1mm. But, what glass gasket would be the better option? The one with an outer diameter of 36.8 (0.1mm too small) or the one with an outer diameter of 37.0mm (0.1mm too large). Again the case diameter for the glass gasket is 36.9mm. I believe I read or heard that the crystal diameter should be 0.1mm wider than the inner diameter of the glass gasket. Is that correct? I'm sorry for all the numbers. I've tried to make it as clear as I could. So, I'd appreciate your thoughts on this. BTW, measuring and sourcing crystals and gaskets is extremely time-consuming! 😓

      Case in point, I just scored a lot of 4 Timex mechanical watches for $15.50 which puts the individual watches at $3.88 each, or £3.09 (or €3.59, ¥28.08 (CH), ¥607 (JP), ₹324 ... or 0.00006 Bitcoin ) 😉
