I do lots of work on Metamecs as they have been based mostly simply down the street from me within the 80’s and Ive met individuals who labored there in addition to seen lots of the vary over the bench.
That is the Zodiac which got here with each variant of motion when it was produced. I lot of individuals suppose which means a quartz conversion must be straight ahead however generally it’s not. This specific clock was fitted with the cabled model of the motion so the appeture is greater than large enough to take an ordinary 57mm quartz. What did want doing nonetheless was re-boring the central spiggot gap which was 3mm too small. The face plate wanted the identical adjustment. Its all in regards to the arms on an electrical conversion and I’m fortunate sufficient to have discovered a supply for these that match on the quartz spindle measurement.
Whereas electrical conversions are a bit “clock heretic”, it’s the proper factor to do on a few of these clocks. I normally inventory the unique components to place a clock again to “manufacturing facility” however typically it makes extra sense to place a quartz in for one purpose or one other – normally accessibility and comfort for older prospects.
