• Case: 38mm

• Lug to Lug: 46mm

• Lug Width: 20mm

• Thickness: 11.2 mm

• Made in April, 2016

• Fully serviced just a few days ago by Yours Truly

• NOS C-type balance installed

• Case received all new gaskets

• All sealing surfaces excellent; no pitting of any kind.

• Minor signs of wear, most notably a scratch on the display back

• I lumed the counterweight portion of the sweep hand - looks stock, you can read the seconds at night. It always should have been lumed if you ask me. Looks like it was meant to be that way.

• Comes on a vintage NOS burgundy goatskin strap made by Condor

• Head only - no box / papers / bracelet
