I've no idea about a Pulse/Time computer, but re- the P1 you linked to:
This is all

The same watch sold 0n 25 February for 7750 GBP (Roughly $11890 US).
Besides using the same photograph (now removed from the February listing), the new seller has even used the same text as in the previous auction: "The P1 was the worlds first solid state digital LED watch, hailed in 1972 as a "Time-Computer" using "Space-Age" technology, and the first new way to tell the time in 800 years of time keeping. Only a limited number were sold with film stars and TV celebrities all to be seen wearing them including President Nixon, Gerald Ford, Sammy Davis Jnr, Elvis, Shah of Iran, Sonny Bono, Yul Brynner, and many more. As any LED collector knows, the world premier of a LED watch being used in a film was James Bond using a P2 in Live and Let Die 1973."

The newly listed photograph is however not water-marked, whereas the text in the February auction clearly stated that the photo's were credited to the seller.
The watch that sold in February had a serial #754-280, so it would be pretty easy to check if it's the same watch.
The new seller has agreed to local pick-up (in one of 3 countries), so it sounds legit, but I'd be reluctant to pay someone $14000 more than what they paid 5 months ago! That's a serious mark-up!
Everyone to themselves I guess

What a stunning watch though
