FYI, the lug size is odd 21mm and there is no Grand Seiko strap that fits....
... so you must go after market or custom made strap shop.... (I went for calf press-patterned cheapy version
)
We should play with the strap for bracelet only models so that it stimulates Seiko design team's brain? hahaha.
