Rare Brown 6139-6010 vintage chronograph from October of 1969.
Stainless steel case in quite good condition, with surface signs of use as expected, with bevels still intact and no big hit or mark anywhere.
Clean and beautiful 6040T Brown Proof dial, with lume still in very good condition! Original hour and minutes hands, again with perfect untouched lume material. Original two piece chronograph and subdial hands. Correct Roman day wheel. Original crown.
Caseback has a few deep scratches from careless watchmakers or owners but from what I have seen through the years, not too bad.
Seiko 6139A calibre was just serviced and is ready to be fully enjoyed!! It comes of course with one year warranty as well, as is the case with every watch that leaves my hands.
