Seiko are putting a £1200 premium on the 6Lxx movements compared to the 6Rxx. The new King Seiko reissues are now coming with the 6L but will be priced at £2900 with the 6R model at £1700.

I have the smaller no date King Seiko with the 6R31 and timekeeping has been excellent. It’s currently +30 sec total for the past 18 days and that includes time on the wrist and in the watch box. The 70hr power reserve is also brilliant. Leave it in the watch box for a couple of days and it’s still keeping great time when back on the wrist.
There is a lot of talk about poor stated tolerances of the 6R/6L movements but in reality I’ve found them to perform much better.
