You have done better than me, I looked into this and couldn't find one that would fit. In some ways what would be nice would be to gut the original case and fit a modern mechanism. I have a spare broken clock somewhere, might give it ago |

The problem I see with fitting the mechanism inside the original case is it will need to be removed in the original way if you want to adjust or when the battery dies. I don't think the one I have would stand using the thingy through the glass to set the time often. The battery problem is solvable with a 1.5v supply off the 12v - 2 series diodes in parallel with the clock and forward biased through a resistor should do that. I'd start with a 10k (near to 1.2mA) and see if it runs, but that's a guess. But even with the glovebox inner chopped to bits so the door stays on, changing the time after the battery's been disconnected will be a pain. If you have to take the glovebox door off, it's a real pain. I'm thinking of a bayonet style method to fix the 65mm quartz clock in the hole from the front. Cos the prongs on a standard clock bare on the plastic ring (I think) it won't matter if I put a couple of slots in the inner flange to the hole in the dash - I can still go back to standard and it won't show. A two prong bayonet would be easiest - just glue a thick bar on the back of the clock and pack the side again the back of the dash to make it tight when turned a bit. Just need to put the slots in the flange in the right spot. Graham |

Then there are these Russian clocks. 12v powered Quartz with a front adjuster. So they won't have to come out often. And what looks like the right bulb holder too. Not a terrible price neither: https://www.ebay.co.uk/itm/Luch-Quartz- ... SwVRNbcDyC 2.373" = 60.2488mm 2.552" = 64.8208mm The hole in the Dolomite's dash being about 62mm and the recess in the front being about 65mm dia. So it should fit. Not sure how they mount, but it shouldn't be too difficult a job. Graham |

If you shop around, you can find OE Quartz clocks for the Dolomite; made by the same company, they have 'Quartz' written across the face instead of 'Kienzle'. There's also a variety with no script on the face at all. |

Only ones I can find through Google images that are as described - on Worthpoint and such - seem to be 2" MGB ones. Only these Kienzle electro-mechanical ones and the Russian Luch Quartz ones seem to be 65mm - and the cheapo ones from China I've been playing with. Graham |

I wasn't suggesting you were making owt up, just trying to see what I'm looking for. I take it the one pictured with only W Germany on the front is still electro-mechanical. I've found pictures of ones that look similar with Quartz on them. But the ones that give details seem to be 50/52mm ones from MGBs, etc. There's some 60mm ones from Wolsey's that look similar, but I don't know if they fit either. I've ordered one of the new (presumably old stock) Luch clocks from Belarus to see what is't like and how it fits, etc. There seems to be plenty of them about, and if they're like that old Rigonda stuff, they'll be solid kit, if a bit old fashioned. My dad had a Rigonda valve radiogram (when the rest of us had music centres) that had AFC on the AM channels - there was a servo on the back of the tuning control. That still impresses me as a pragmatic solution to what was then a tricky problem - electronic control of the intermediate frequency generator in a superhet; especially one made of bottles. Graham |

Ah, it wasn't Alexander Pope that said "To err is human: To screw-up completely takes a computer". Though I do like the quote I recently saw from Edgar Allen Poe's The System of Dr. Tarr and Prof. Fether: "Believe nothing you hear, and only one half that you see on the Internet". Some of the non-runners can probably be fixed, given there's a fairly common fault in the supply link to the solenoid that's fixable with a drop of solder. I've also discovered that the ones that run too slow or too fast to be set from the adjustment on the back can, at least sometimes, be fixed by a couple of internal adjustments. I also found that if you take them cheap Chinese quartz clocks apart the, escapement does exactly what it says on the tin. However, both the fixes to the Kienzle clocks mean uncrimping the chrome ring from the flange on the steel body. And that's not easy to do without cracking the ring, or so I've found. As to the 12V supply, I'm using one of the PSU-in-a-plug jobs for LED strips and a socket got off eBay, with two Lucar connectors crimped on the flying leads. Graham |
