Nice clean example of a Vintage 1968 Seiko 6105-8000 Slim Willard proof/proof automatic watch with Rare Original ZLM01 Waffle strap Been serviced as can be seen Comes on an Unkle Seiko waffle strap Original strap is still pretty flexible but has become hard which is common You can date the watch from the serial number on the back of the watch to May 1968 ( retro seiko.co.uk ), and you can check the legitimacy of the strap by looking at images on plus9time.com Any queries please feel free to ask Watch has been working fine since it’s original service, and was worn daily - another project forces it’s sale to secure funds for an Omega watch I have listed it as seller refurbished but that’s all I have done to the watch since owning it many years ago is to have the service done on the watch by Richard Askham, which outlines the work done to the watch Free Special Delivery postage
