The Rolex Oyster Precision is judged to be original and period-correct in its main configuration.

[Features]
Rolex Oyster Precision Ref. 6426 / cal. 1225 (non-hack) / 21,600 bph / 34mm case / 19mm lug
Year: c. 1969 / Serial No: 228xxxx
30m water-resistance test passed.

[My impression]
This is the no-date Rolex Oyster Precision Ref. 6426.
At around 10mm thick, it wears noticeably slimmer and dressier than the Oysterdate Ref. 6694.
At the same time, the relatively large 6.0mm crown gives it more presence and makes winding easy.
Personally, I prefer the 6426 to the 6694.

[Dial] : Very Good
It appears original. No clear signs of redial, repainting, or relume. 
All tritium dots remain.

[Hands] : Good
They appear original, with no clear signs of replacement or relume.

[Crystal] : Very Good
Plexiglass.

[Case, crown and back of the case] : Good
The case shows age-related wear and appears to retain its original shape.
Crown screw-in is very good (approx. 1.6 turns to unlock). 
Serial engraving is clear.

[Band] : New
New aftermarket leather strap, not Rolex.

[Action] : Very Good
Hand-winding and time-setting work properly.

[Accuracy] : Very Good
About -8 to +8 sec/day. (Measured by Timegrapher)
