This is one of Torsten’s watches – a Junghans DayDate with a Durowe 7526 movement. It’s got a lovely blue dial and a gold coloured case, and the watch is in very good condition.
Let’s see what the movement is doing …
Not much 😉 Very low amplitude, and the movement beats too fast.
A first look at the Junghans 653, which is actually a Durowe 7526. A great movement with a unidirectional auto winder.
The day and date mechanism with quick-set for both day and date.
A very snappy date change.
Time for the top plate.
Auto winder and balance removed.
The gear train.
The old mainspring.
The old mainspring is not level and quite deformed, so I will put in a new one.
All the parts go into the cleaning machine.
The new mainspring in the barrel with the old mainspring in the background.
I start off with the balance jewels.
The base movement is beating.
And that looks very good indeed.
The auto winder bridge.
And the bottom plate goes back together.
The date ring is in place.
And now the day.
Dial and hands back on.
And I case the movement without the rotor.
Final adjustment.
Great looking watch!

Hey verry impresive, youre work here.
I have a question about the autowinding. The rotor, is there a bearing under it. Because i bought the same watch and the rotor isnt center of the caliber. It grinds on the bottom plate of the movement and even touches the balance wheel.
The rotor has a jewel bearing. If your rotor is loose, something is definitely missing.
That case is in gorgeous condition for a 40(?) year old watch… and the dial patina (assuming it isnt part of the original design) is rather nice as well 😉
Did the movement perform that well in all orientations? Also pretty impressive!
The usual variation between positions (about 10s or so), but a very good amplitude throughout.
