  1. the info on the “Aliens” watches is incorrect. Ripley wore a 7A28-7000. Bishop wore a 7A28-6000. The pulsemeter was an S229-501A. And here’s some new information: Burke wore an H556-5050.

    • Thanks for the email! You’re right, I goofed on the module number it is indeed a 7A28 and not A728. I will fix that. I wasn’t aware of the H556, that’s interesting–I’ll have to give it a second look.

      Seiko did make an S229 and I had that impression initially too. But looking carefully at the display, it matches that of the S234–the “bump” in the line separator appears in the middle. The bump on the display on the S229 is on the left side.

      • Ha, yes I was sort of wrong about the Pulsemeter – I had to go downstairs to get mine. Shows I shouldn’t go from pure memory. They wore the S234-501A (I was half-right), and here’s mine: http://i.imgur.com/hylZZ81l.jpg

        The H556-5050 I found along with another collector – after looking at Seiko catalogs and comparing models with screenshots, this was the only one that fit. It’s the one.

What do you think? Please tell us!
