Vintage Seiko Automatic Chronograph

Seiko used to produce pretty good automatic chronograph back in the 1960's and 70's before the Quartz revolution. During the time the chronographs were relatively cheap compare to their new Ventura, Credor, and Flightmaster automatic chronograph. My personal opinion is that these vintage chronograph is value for money... not only are they stylish... the case, the movement and the finishing is of high standard... I think the reason for ceasing production may be due to the costing factor and also the shortage of skilled watchmakers to assemble all those movements...

Seiko still makes excellent mechanical chronograph nowsaday... but the price is way above the sky... if I am going to pay that amount of money, I will opt for Breitling, omega and IWC chronograph. Afterall, I find the european cosmetic is much nicer. There is always talk of in house movement and a lot of experts are emphasizing on that term.... but if a movement is reliable why not?

Classic Seiko Bullhead

Seiko 6138-0040 (Brown; Speedtimer)

Speedtimer is only for Japanese market and is usually consider to be of higher standard than normal bullhead chronograph. This is a pure blood bullhead... all original even with the speedtimer buckle. Bullhead is a double registered chronograph.

Seiko single registered chronograph 6139-6020: The doctor's watch

This is a 17 jewels automatic watch with day date function. This watch was made during the early 1970's. I picked up this one from a local watch shop as a new old stock. Therefore everything is in original status... sadly there isn't any instruction or manual left for this. What is distinctive with this chronograph is that rather than having the normal tachymeter, it has a Pulsimeter. How to use the pulsimeter? Don't ask me... I am not a doctor by profession... However this is what I found out from the internet:
This watch was aimed at members of the medical profession as it can be used to measure heart rates. The outer ring is graduated with the numbers from 100 to 11 and the ‘base 10′ tells you how many heartbeats to count before stopping the timer. To use it, you feel for the patient’s heart beat, reset the chronograph, start the timer, count 10 heart beats and then stop the timer. The number that the sweep second hand points to on the outer ring is the patient’s heart rate (in beats/minute)….
