Seiko Dolce

cal. 8J41

Factory Spec. 10 SPY

Thermocompensated: Thermistor

User Adjustable: No

I picked up this watch for an example of the 8J movement. It was the movement formerly used in the Grand Seiko range and which can still be found in Credor watches. It is a lot smaller than the very substantial 9F movement that replaced it in the Grand Seiko line-up, but still delivered 10 SPY. One of the major downfalls of this movement is the problem of rate adjustment. I believe the rate is probably adjustable somehow, but not by the user. And I do not know how far into the future Seiko will continue to service these movements (or even if they currently do) to bring them back to spec..

Some details for this watch may be missing as it has not yet undergone comprehensive testing.
