Guys, I found out about this community just yesterday, and I had to register, so count me in! Here's a shot of my freshly serviced 6139-6020! Seems like we are just a few, I don't see this reference around much.

Looks like a dead thread, but I came across it while looking for more info on the current object of my desires, a 6139-6022. Maybe the thread will rise again... I’m a cardiologist and have absolutely used the pulsations bezel I added to my Speedmaster Pro to check a patient’s pulse. Did I need to use it? Absolutely not. But it is nice to not have to watch your watch while counting the pulse.

Doc can you post a photo of the pulse rate Tachy bezel? We would love to see how it is laid out.
I compliment you for modding a Speedy Pro, too !

I didn’t know if it was kosher to post non-Japanese watches. The red-tipped seconds hand is a nod to the red “12” on medical watches of old. The second pic is was taken during a break in clinic today.

Doc, you're on topic so the brand doesn't really matter. Nice watch

Base 15, ranging from 40 to 200. So by comparison it becomes clear that the 6139-6020 is for other purposes.

I was disagreeing with the comments that nobody uses a pulsometer to check a patient’s pulse. I agree that continuing the scale so low is very unusual and may be to accommodate other uses. I’ve not seen another pulsations scale that goes below 30 or so. I had previously assumed Seiko did it for dial aesthetics/“symmetry.” I have read (have not had the opportunity to experience one in the metal) that the 6020 and 6022 have lower profile cases to better slip under a dress cuff; if that is true then it is at least plausible that they were intended for medical use. Regardless, glad the thread is revived, and thanks for the info!

I think I need to weigh in on this subject as I am a clear expert (insert tongue in cheek emoji) Despite not owning one of these watches (looking for a generous benefactor) I can say with certainty they can be used for both. Exhibit a- heart rate monitor (real pt, real heart attack consent obtained) Exhibit b- donut timer. (Real donut, real donut chef, consent obtained.) I am 100% certain I have seen a 1970’s catalog for the 6139 being sold as a drs watch and tool for quick pulse assessment. I will find it. To be fair it’s absolutely useless as life saving equipment as following a bit of practice I can tell you in 3 sec your pulse rate to 5 beats per min and diagnose a few heart conditions.

Just to keep this old thread that got revived a bit on original track, the 6139-6022 has a rotating inner pulsations ring.
Why wouldn't it be fixed if its purpose was solely to be read using the start/stop sweep second hand? That would be totally unnecessary.
Clearly this one extremely versatile and extra special tool watch in the world of already special pulsations tool watches. Featuring an rotating inner pulsations ring the 6139-6022 allow for it to be used in 2 different modes:
A. Pip lined up with 12 o'clock, start the chrono, count to 10 and use the seconds hand to measure in units per minute. Just as you would if it had a regular fixed pulsations ring.
B. Rotate the pip to match up with the tip of the minute hand, count to 10 and use the minute hand to measure the output in units per hour.
Yes sir the 6139-6022 is a truly rarefied ultimate tool watch !

Speculation - What if it's meant to time maritime radio pulses? Or pulses from a some sort of emitter? The commies did a special dial for the Komandirskie that had sectors on it for sending the cold war radio pulses. Just to keep this old thread that got revived a bit on original track, the 6139-6022 has a rotating inner pulsations ring.

HiBeat I think this was to establish a quirky feature to an already established market. Other watches had this feature I’m sure. I’ve had stupid non chronograph non adjustable pulsation nurse watches. It was a pain waiting 45 secs for the second hand to re align to 12. I have actually tried the pulsation watch to measure. You take your left hand, reach over and grab someone’s pulse. With your right hand you adjust the rotating bezel to the current second position. It’s actually harder to stop reset and start the chronograph. I have tried this also and I get nervous with excessively messing with the clutches of a mechanical chronograph
