In case you want to refurbish what you have, there is still a repair shop that takes them, and it's mentioned here, but just to update that information. It is www.walthamclocks.com. They open at 10. When you call 334-774-3584, use extension 100 and even though it says voicemail, I have gotten a live person each time. Not cheap. My rebuild is $350. I last had a rebuild 20+ years ago for $150 so that's about right. They're not to be confused with the clock builder Waltham Clocks, which was in Waltham MA and went out years ago. The repair shop is in Alabama and still in business at this writing, March 2024. Mine is a swiss one, probably Breitling, though there are ones made by Wakmann and some labelled Pioneer. Don't know if they repair all types but worth a try.

Sorry for not putting this in the For Sale and Wanted section but I expect it will get more response here. The title is the question. I fixed up an Astro Tech which I love, but it won’t fit in the center of the old style F yoke. I would even do some swapping for one. I also would be interested in a timer if it is one that is known to fit the yoke. If you know of a model that will for sure fit in the yoke, I would appreciate knowing the make and model. Thanks for your responses.

https://mooneyspace.com/search/?&q=Clock&page=2&search_and_or=or&sortby=relevancy The search has also uncovered the ‘hot keep alive’ circuitry, and what else may be attached to it... briefly... Around MS... you will find people that like their clocks... From... Wakmann 8 day clocks... Astro-tech LC-2 Aerovonics AV20, AV30 (fancy back-up AI with the clock) Davtron 811B A13A1 ? Mid continent MD93 that has USB ports on the front.... Aviation clocks are expensive jewelry, since my iPad does all the timing functions I need... Might as well get something certified, digital, and comes with extra skills... The aerovonics entry has many skills... but don’t trust the sensorless AOAi for anything but a parlor trick... PP thoughts only, stuff I have read about here... Best regards, -a-

In a one word answer... yes... Clock cleaning and lubrication can cost a few bucks... Sounds like you will be happier with a more modern digital solution... If you have a few mechanical watches and a grandfather clock that requires winding, at home.... this is a perfect addition to your collection... For more detail about your clock... find the word wakmann around here... https://mooneyspace.com/search/?&q=Wakmann&search_and_or=or&sortby=relevancy Wakmann belongs to a big name in time pieces... Best regards, -a-

Darn autocorrect, Yes, I meant Wakmann.

I think you mean: Beechcraft, Wakmann Analog Clock: I have one in my hangar if you want it, make me an offer... Tom

Wakmann if the spelling helps with the search... Siri wants to respelling things all the time. getting one fixed, needs an old time watch/clock guy... Best regards, -a-

I have a cool Wakmann 8 day 7 jewel clock for my yoke. I wanted to get it working because I just think it is cool. I opened it up to see if I could get it working and found a couple of issues that require new parts, so it would need to go into a shop to get serviced. I was about to box it up to ship and realized the dang face has a Cessna logo on it. Blasphemy! Did any of the 50’s or 60’s Mooneys come with a mooney logo 2.25” wind up clock? Anyone have one that they would let go?

Mine said wakmann right on it. If it died, I kNew it was time to go flying... more often... Somebody has started a thread around here already regarding where to get wakmann service. one part instrument shop to get a nice logo printed on it. One part clock shop to get the right bearings and springs... Best regard, -a-

Is it a Wakmann? The movements are (were) made by Breitling.

Are we talking the Wakmann in the yoke? My hangar elves dunked mine in mineral (clock/sewing machine) oil overnight then magically drained all the oil off and stuck it back in. Has worked perfectly since. Of course, I only use it to time my tank switchovers. It's just too cool to remove.

Yes, but the yoke appears to be sintered metal so proceed cautiously. Like I said, mine already had a hole. I was/am of the same mind. When I got my E the yoke clock didn't work. One day I discovered that the hangar elves had soaked it in clock oil (fine mineral) overnight. It has worked beautifully ever since. Few know that Wakmann used a Breitling mechanism for this clock! If truth be told, I just use it for quick reference and to time my fuel switchover with the handy red timing hands.

I own a 1966 M20 E and when I bought the plane five years ago it came IFR certified with pretty much the original panel. Since then, I have added an EI MVP-50 to it, removing most of the original engine gauges and such along with the DME and ADF. The later two removals were in anticipation of a WAAS GPS system, but that has yet to materialize. The original panel included the ADF, but ADF is fast disappearing from US approaches. As such, I am left with dual VORs, one of which has GS. The original panel came equipped with a marker beacon receiver and an audio panel for switching two radios and the ADF. Since the pilots yoke is equipped with a second-hand precision (Wakmann/Brietling) clock, I will argue that this aircraft was built and sold for IFR flying. Additionally, pitot heat, which some master CFII's will contend is the most important piece of IFR equipment, was included as well as a huge vacuum gauge right in the center of the panel. The PO added a backup vacuum system that runs off the intake manifold. What puzzles me is why there is so much fuss over the "six-pack" panel. If a guy bought this plane back in '66 and flew it for years IFR with the panel layout as it was, why would redoing the panel now make any difference? Here is what I have: The "scan" is very important to the IFR pilot. With this panel, you scan the ASI, AI and DG across the top. Then the TC, Altimeter and VSI along the bottom. You can't miss the vacuum gauge and the VOR/GS is only looked at enroute and during an approach. So, what's the problem with this?

The old clock is c I just find my Wakmann to be just oh so cool. While I love technology just something so great about that clock.

Oh the humanity! ...err, I mean the inaccuracy. I will bet that the seconds on those old Breitling/Wakmann yoke clocks are off by at least a millisecond/second.

It's likely a Wakmann 8 day clock. Take it to a jeweller who does clock or watch repairs to get it fixed. Once running again they can be calibrated for accuracy through an access cover on the back. Clarence
