Overhaul of a Rolex Vintage Oyster 6426 caliber 1210 watch
Joshua GrilletToday it's Rolex on the workbench.
A watch in the shadow of the iconic models of the crown brand. It nevertheless remains appreciated by collectors because its price and its diameter are contained, but also for its finesse and its beautiful proportions.
The Rolex 6426 Precision . Oyster bracelet, Oyster case, mechanical movement with manual winding and crazy patina! This model is from 1969 according to the serial number. 34mm in diameter and 19mm lug length, the beautiful vintage for every day.
_______
State of play
Mechanically, this watch is not in good shape. In fact, 2 turns of the crown to wind it and a *clack* is heard. An idea of the problem ?
We'll see that.
_______
Disassembly
With the specific tool I can open the bottom. The seal is dead but the movement is in good condition. A Rolex 1210.
Under the lens it's not a pretty sight. A nice mix of grime and rust.
All movement parts are inspected before being cleaned.
As you may have guessed, what interests us is the barrel spring. It is he who gives the driving force to the rest of the watch. The spring must be removed from the barrel to inspect it.
By removing it, we can see that it is broken at its flange. As a result, it cannot remain correctly in place in the barrel during reassembly. Spring replacement is inevitable.
_______
The reassembly
The barrel spring is replaced with a new one.
Let's go on. 
_______
Conclusion
Unbeatable precision, a simple revision is enough to restore its letters of nobility to this little fifty-year-old Oyster.
Along with its Rolex Oyster 7835 bracelet in folded steel, it now accompanies me (almost) every day.
Take care of your vintage watches, they deserve it.
