This vintage Seiko 6139-6012 wristwatch is a classic piece with a unique twist. The watch features fixed bezel inside on a yellow and black dial, with a chronograph function and day/date display. The stainless steel case has a screwback and measures 39mm in size, making it suitable for both sporty and dressy occasions. The watch is a mechanical automatic movement and has a left-handed orientation. It does not have water resistance capabilities  due to the age i wont consider it water resistant, but does come with a seller warranty. The Seiko 6139-6012 model was manufactured in Japan during the 1970s and is a must-have for any watch collector looking for a unique timepiece. remember using the vintage we can help in less carbon emissions, thats why i love most of the vintage stuff, i will send the watch in an used cardboard box with paper and stuffing ,thats my share for helping the environment thankyou.
