There seems to be a bit of confusion regarding the relationship between the Hamilton Watch Co. and Time Computer, Inc. The popular perception seems to be that Hamilton owned Time Computer. It did not. Both were owned by a parent corporation, HMW Industries. Thus it is not surprising that TCI supplied modules for Hamilton-made watches [their arrangement with Omega was similar, but I'm sure it involved a lot more negotiation]. And while there are no Hamilton watches with Pulsar markings, there are Pulsar watches with Hamilton markings, making them a true "Hamilton" watch.
The entire production run of 400 P1s bears the Hamilton name on the case back [as well as the 5-pointed star indicating the case was manufactured by the Star Watch Case Co.]. It seems reasonable to assume that the Time Computer manufacturing facility was not yet up and running in early 1972, and there was tremendous pressure to get some watches completed and on the publics' wrist [they correctly guessed that whoever was first to do so would command the lion's share of the market]. Being "sister companies", it would have been a straightforeward matter to enlist Hamilton's co-operation in that effort, and in exchange, that Hamilton would request that their name also appear on the watch [and since it would have benefitted both companies, Hamilton thus associating itself with a revolutionary new technology, and TCI becoming connected with Hamilton's name and established reputation for quality, Time Computer could hardly have refused them].
So, besides the P1s, are there any other Hamilton Pulsars? Actually, yes!I had thought not, but a while back, while preparing a [goldfilled] P2 for restoration, I noticed the caseback was marked "Hamilton Watch Co.". This was a watch that was certainly totally original, as it had not been worn for nearly thirty years, and had been obtained from its' original owner. It had a very low serial number [11XXX, and it is important to bear in mind that the serial numbering started at 10001; I have not heard of any P2 with a serial number lower than that...if anyone has one, I would very much like to hear about it!], and the rare finger-tab type magnet door. So it would seem that a limited number of P2s were also assembled at the Hamilton factory. Once TCI was able to assemble watches on their own, there would have been no further need for those watches to have Hamilton markings. Judging by the frequency of their appearance, I would guess that the Hamilton-assisted period was quite brief. No models besides the P1 and P2 are known with Hamilton markings.
The question now is: How many are there? Serial No.? SS or GF? This inquiring mind wants to know.....
