Here is another variant of Seiko 6138 chronograph. This is somewhat smaller in size compares to Bullhead and UFO. It was made in Japan in 1976. I classified this as standard sizing for those with smaller or medium size wrist.
The stainless steel case is measuring 39mm without crown. The watch has a black dial with blue subdials and blue wordings. The hands and subhands are in white.
6138 has a quickset day and date. The first pull of the crown adjusts both with ease. The crown and the pushers are all stainless steel. The first pusher at 2 o'clock is to start and stop the chronograph function. The second pusher at 4 o'clock helps reset the chronograph.
The watch has a tachymeter ring to give it a more competent sporty look.
See how shinning and beautiful is the stainless steel case? This watch still with original Seiko bracelet.
The backcase is pretty simple and with the watch serial number and the model number engraving on it.
For me any vintage Seiko Automatic Chronograph that still functioning normally and is in descent condition worth to have a look.
