SOLD - NOS Seiko Speedtimer 6139-7020





Seiko's lineup of Speed Timer chronographs is renowned for its exceptional vintage racing timepieces, but acquiring one can be quite challenging due to their exclusive availability in the Japanese market.


Featuring a 21-jewel variation of the esteemed 6139 movement, these models surpass their international counterparts and offer distinct features. The showcased 7020 model from March of '71 is truly captivating. It showcases a deeply recessed matte black dial with a split, two-tone sub-dial in black and vibrant blue. Positioned prominently in the middle of the dial is the "Speed Timer" logo, contrasting the black-framed day/date window that can display either English or Kanji characters.

The minute track, adorned in striking "Speed Timer" orange, serves as a perfect division between the dial and the glossy black countdown bezel, which can be adjusted using the crown. The outer bezel features a black inlay, and the tonneau-shaped case is designed for comfortable wear on the wrist.


The example we have available is in pristine New Old Stock (NOS) condition. Don't miss out on this exceptional timepiece, as it is unlikely to remain in stock for long.


Please note that since this Speed Timer is in NOS condition, it will be sold as is. However, servicing is possible for an additional cost of 40,000 JPY. Feel free to contact us if you would like to proceed with the servicing option.
