1977 SEIKO - Bullhead
Chronograph Automatic
Vintage Wristwatch
 
Seiko started producing the Bullhead model in the early 70's as part of the  “Seiko 5” family and finished the production in the late 70's. This model was produced, principally, in two colors combinations on the dial and has its name from the orientation of the crown and pushers on the top ("head") of the watch at 12 o'clock position, giving the chronograph pushers a resemblance to the horns of a bull.

Today, we offer this vintage Seiko Bulldhead chronograph automatic wristwatch in the brown/gold dial combination, reference 6138-0040 and dated from August 1977.

It is a self-winding watch powered by an original Seiko automatic chronograph (30 minutes – 12 hour) movement. It features the caliber 6138, 21 jewels, day/date indicator (2 languages ), 45 hours power reserve, 21,600 A/h, Japan made.
 
After 45 years, this watch still has the original brown dial with white/luminous baton hour markers, white minute/second track, white/luminous matching hands and yellow sweep second hand for the chronograph as well. The day/date window is located at 6 o’clock. The dial is also signed with the Seiko name/logo, "Chronograph" and "Automatic" on top.

Cased in a 44mm cushion case, all in stainless steel. Non-rotating tachymeter bezel (a scale which drivers use to measure speed over a given distance). Water resistant.

This watch also comes in the original Seiko all stainless-steel fold over clasp bracelet, it will fit a wrist up to 7 1/4” (18.4cm).

It is a very good looking watch. Runs very well and keeps great time!

Vintage watches are traditionally smaller than today's watches. Men’s watches typically measure between 29-36mm wide (some larger, some smaller) excluding the crown. In the listing details we typically try to do our best to list all pertinent dimensions of a watch. If you don't see it, or we failed to do so, please reach out to us. Women’s watches from the 1900s-1970s were also much smaller than today's offerings. Please also feel free to ask any questions you have pertaining to size.

We prefer to shoot photographs outside when weather is permitting. However, when we shoot indoors, please be aware that we shoot our photographs inside of lightboxes that are lit with 360 LED bulbs. This indeed magnifies any flaws. Usually, they are much less obvious to the naked eye. Having said that, we never photoshop any of our photography, remove blemishes, etc. We adjust lighting when necessary, but what you see is what you are getting, and we take pride in that.

The condition is pre-owned.
The item may have some signs of cosmetic wear but is fully operational and functions as intended.
Please review the photos and feel free to ask any questions you may have.

It will be carefully packed.
