  1. Need sme advise just bought a mint lynx alarm caculater watch date on it says 1980 hve seen alot like it but not same square black plastic lynx across top any idea of its worth?

    • I own the Sanyo Alarm-Chrono (only basic features, not the scientific one) too, and i don’t have the official manual, too. But i may be able to help with your specific question: Pressing the MODE button for a longer time cycles between Alarm-, Time- and Date-setting mode. When in Date setting mode, pressing the SNOOZE button moves the dot-indicator for the day-date.

  2. I picked up a watch that I cannot find any info on: Hitron alarm calculator watch. It works, if I can find the odd sized battery for it, in fresh condition. Any info out there from you all?
