Lug to Lug: 41mm

Thickness: 9.3mm (including crystal)

Movement: Seiko 4520A Manual Wind

Some scratches along the case and crystal. Small ding on the case (top left lug). Dial has some patination around the 2-3 o'clock position and a spot just below the 8 o'clock marker. Indices, hands, and sunburst dial are in great condition. Movement is very clean and keeps great time. Amplitude indicates a potential need for a service in the future, but it works great as is. 

This Grand Seiko will ship with a grey wool strap, but looks great on almost anything! See pictures for what it looks like on a blue calf leather strap.

Sourced directly from Japan!
