In high school, I was the kid that synchronized my Casio Databank to the school bell on Monday morning, sometimes (but not usually) impressing classmates with my exact knowledge of when the bell would ring.
One thing that you realize if you’re an accuracy freak is that standard quartz watches almost always run slightly fast, something around a quarter second per day. If you set your quartz watch weekly, you’ll be right near two seconds fast. I’ve always wondered if I could get a watch that would allow me to trim off a quarter second per day and improve the accuracy. Even just shaving off a tenth would give me superior accuracy to a regular quartz watch.
Alas, I browsed the HAQ forums over the years without any solutions. I even bought a couple of (relatively) affordable HAQ watches to appease my love of accuracy: The Longines Conquest VHP and Tissot PR-100. Both also added seconds, though there was at least an order-of-magnitude improvement in performance. But their rates can’t be adjusted, and I just have to sit idly by as each gains around a second per month.
I know that some watches, like Casio G-Shocks, have trimmer screws that allow you to adjust the rate. However, they are extremely sensitive, and I never really wanted to mess with them. Why not an option to digitally trim: how much software would that take?
I recently stumbled on a solution to my desire, and to my surprise it was cheap. Old Soviet Elektronika digital watches actually have a digital trimmer menu in tenth-of-seconds per day increments. Only certain models have it: models 53, 54, and 55, but they can be purchased on eBay for around $40.
I bought one, and after some monitoring I trimmed my Elektronika 53 back 0.3 seconds per day. My goal is to regulate this watch to within 5 seconds per month. I know 60 spy isn’t exactly HAQ territory and that there is no thermocompensation here, but it’s a fun cheap option that might get you accuracy somewhere between a regular quartz watch and an HAQ.
Has anyone else messed with these watches?
