A Seiko 6105 ‘Captain Willard’ was in for restoration. As you can see, the movement was in a pretty filthy condition. The mainspring had old oil and filth caked on and looks much better after cleaning.
I also performed the lower and upper jewel upgrade, which is a must these days. I also jeweled the second wheel.
The crown was rebuilt with new gaskets and its now waterproof once again.
You can see from the before and after pics how crucial it is to overhaul your watches. But a testament to the quality of these vintage Seiko’s is the fact that after all these years of dirt and filth, not a single worn pivot in the gear train.
