From where I am, to ?

Sorry if I've upset you, but it really isn't vintage. The Pulsar, however, would definitely be one. Pics of that would be awesome.

I am not upset, perhaps a little embarrassed about me being a fool and easily fooled. The battery should have been a tell, to begin with...
What puzzled/confused me a little, is that the case is stainless steel and machined from one piece. Unusual for an Asian, me thinks. Or?

No worries, Michael. We've all experienced that at one time or another.

The battery is the biggest tell. Second would be LED WATCH" on the front. Vintage ones never needed to say what they were. They just were. Third is the very modern text/font on the caseback.

There are some modern LED watches that aren't too bad. These ones below have a decent case and use LED technology similar to the vintage watches. I had one of these, but it still doesn't compare to a true vintage LED.

Rare Rolex LED watch (prototype)

source: Electrifying the Wristwatch

book by Trueb, Ramm, Wenzig; Die Elektrifzierung des Armbanduhr.
Op page 183 they even produce a photo!!!

In 1975 and 1976 a team of three engineers travelled to the US to source parts for a LED watch on behalf of CEH and Rolex.
The joint idea which they went sourcing for was a LED watch with a Forme Analogique, analogue display.
With the results CEH want one way and Rolex another although they did share the further development of the basics.
CEH decided on a permanent display with solar cells to provide extra energy and Rolex decided on display on demand, thus omitting the solar panel.
The hour ´hand´ was indicated by 4 LEDs in a row and the minute ´hand´ by 7.
The engineers developed it all the way to pre-production and produced 5 complete prototype watches in 1978.
Bossman Heiniger however dicided that it would not be compatible with the classic mechanicals and binned the project. He was after all in luxury goods, not in watches.

So it díd exist!
... and were distroyed

There is quite a bit more very surprising info on the Rolex participation in electronics in this book. I was véry much surprised to learn how many differently engineered prototypes they developed but most by the fact that they participated in several seperate joint ventures. Sometimes even with bóth Rolex Geneva and Rolex Biel as two participants in the same venture.
It is also the only source whih I have found sofar that provides detailed info on the quartz calibers used in the Celline range. Technical but also per example that from 1990 till to date some 100.000 cal.6621 were produced.

Disappointing to read is that they binned two very promising projects to develop a high accuray quartz caliber:
They bought 1000!! 2.4 MegaHertz Z-cut quartz resonators from CEH in 1984 with which they developed a véry accurate caliber of which prototypes 50 were produced that only deviated a few seconds per year.
The other was a twin quartz with a standard 32kHz oscilator and the 2.4 Mega. The 22mm. 3V Lithium battery gave 10 years pr. This caliber brought it to a fore-series of 400. This is the caliber which is illustrated on Oysterquartz.net.
All were scrapped. Heidiger undoubtedly realised that the luxury mechanicals would be in their underpants if he brought these contemporary tech high end calibers out. He was after all in the business of making money, not watches.
