I’ve been eyeing the SLA051 for the last little while, and it’s really a beautiful watch in my eyes and ticks a lot of boxes. The only problem is, the specs read, and it looks huge by my standards.

I have no way to see one in the flesh before committing, so i pulled out my calipers to try and see what I do have that’s semi close in size. By my measurements, it would seem that the Seiko is only a mm at most (and likely less) larger in most dimensions than my Citizen eco drive promaster…
