We’ve seen the alpha on this blog before, but not yet the beta, so it’s about time! Steven sent his watch in for a service, as it’s not performing any more as it should.
The Nomos beta calibre is based on the alpha (which is based on the Peseux 7001), and has the additional feature of a date display at 6 o’clock.
The nicely etched case back.
Yes, this watch definitely needs a service!
The gorgeous Nomos beta.
Now here is the smart bit – Nomos wanted to fit a nicely readable date disc, and so decided to make the inner diameter of the date disc as large as the outer diameter of the movement. This gives it extra space, and allows nice big numbers. Great if you are getting older like me 😉
With the date ring removed,you can see the date change wheel and the intermediate wheel.
The gear train with the hacking lever coming down from the sliding pinion.

All is cleaned, and I can put the movement back together with a new mainspring.
The gear train is in place.
The winding and setting mechanism is back in, and I can wind the movement for adjusting.
Now that’s more like it. The beta performs as well as the alpha, and has very little positional variation. These are great little movements.
Now the date mechanism goes back in.
The movement has a large case ring, which holds the date disc at the same time.
The dial and hands are back on, and I can case.
A final adjustment and a new case back gasket, and we are done.
I have my eyes on a Nomos automatic date, but I’ll have to save up a bit 😉 Nomos makes great watches, simple, reliable, accurate, and, best of all, they supply parts to independent watch repairers like us!
