Tamer contacted me, as he had bought a batch of NOS Double Rhomb watches. The interesting bit was that they came in their original packaging!
This watch probably dates from the early 80s, as the dial is already in Chinese and English, and the movement is the 17 jewel Tongji.
The watch is in immaculate condition, straight out of the box.
After over 30 years in the box, this is pretty good. The amplitude is a bit low, but performance is still good!
First look at the movement – very clean, just no lubrication left.
The dial is immaculate.
And so is the bottom plate.
The gear train. The central second construction is well made, with the fourth wheel jewelled on both sides.
I will re-use the mainspring.
All the components cleaned.
I put the balance jewels in and oil them.
The mainspring goes back into the barrel.
Now I put the gear train in.
The top plate is complete, and the movement is beating.
That looks nice – good amplitude, good, constant beat rate.
Now I can put the bottom plate back together.
Ready for the dial.
And the watch is back together again.
The bracelet isn’t of great quality, but the watch is a solid, good piece of workmanship.Back into the original case.
