If your budget is a bit more, and you want to hear a massive clunk every 30 seconds rather than a soft tick and you want to drive 2' (60cm) hands, then you might want this: https://waitingtrain.blogspot.com/2015/05/a-large-gents-turret-slave-movement.html https://waitingtrain.blogspot.com/2015/05/a-large-gents-turr...
The smaller ones look the same but are less beefy.
I used one to make this clock:

Which instead of using a well disciplined time source, uses a tuning fork and 74xx logic to drive it
- smithza 8mo agoThe DIY tuning fork clock is very cool. I am hard pressed to understand why accutron doesn't still make and sell tuning-fork watches. I really admire the creative use of resonance frequencies (not dissimilar to quartz watches but cool that you can really see the tuning fork for you watch as opposed to a diminutive quartz crystal).
- dole 8mo agoThey recently re-released the Accutron with actual tuning fork movements, but at $6k ofc you’re better off buying vintage: https://www.hodinkee.com/articles/introducing-accutron-314 https://www.hodinkee.com/articles/introducing-accutron-314
- KaiserPro 8mo agoThey have done a re-issue, which Dole has linked to (I'm not going to lie, they do look smashing) I think the reason why it took so long is a combination of snobbishness (its not "mechanical" enough) and cost of manufacture. I assume that most of the tooling has been lost, and it required a lot of work to re-learn how to make from scratch. But accutrons wern't that cheap when they launched, so I think they are within 50% of their original price, judging by my half arsed inflation calculations.
