QT-99 for sale on eBay but already gone

I searched but could not find the post from someone here recently that was lamenting not having a QT-99. Maybe it was a DM and that’s why I can’t find it (no search capability there).

Anyway, when I was going to bed last night eBay emailed a hit on a saved search for a QT-99 for sale. Even though I have one I guess I never deleted the saved search. This is the first chance I’ve had to come here and post it for whomever is looking for one, but sadly it has already sold. I say “sadly” but if…

High availability power for devices, and power stations to make them portable

Over in the “2nd Annual WatchUSeek HAQ Florida Get Together held Sat., May 24, 2025” thread I mentioned that I had used portable power stations, combined with a power supply redundancy box I made, to be able to move my GPSDO from my house (where it had been online and “disciplined” for months) to the car, without the GPSDO losing power and starting from scratch. I didn’t go into too much detail because I indicated that I’d do a…

2nd Annual WatchUSeek HAQ Florida Get Together held Sat., May 24, 2025

OK, it was really just @Mandaue and I getting together for lunch while he was visiting Florida and we were within reasonable driving distance of each other. We met the same place that we did in February of 2024, but with a vastly expanded agenda.

This year we came prepared, both bringing gear to let us do some experiments and hopefully learn some things. We knew we’d need the…

Latest Longines Conquest VHP – fixing improper date display

I debated adding this to the end of the Longines VHP Hand Alignment Question thread but felt that it might be easier to find for whomever might need it in the future, realizing that future person might even be me. :)

A friend of mine has the same Longines Conquest VHP Chronograph that I do – except his has the blue dial while mine has the white.

Just so we’re all…

If you think GS bracelet screws are small…

In various threads we’ve discussed how tiny and easy-to-lose the GS bracelet screws are. For something that actually needs to be manipulated now and again they are indeed quite small.

But if you think GS bracelet screws are small, you’ve never had to install or remove rate adjusting screws from an early 1970’s Bulova Accuquartz. Those things are so small that you really have to wonder what infernal device they used to machine them.

For those of you who may not have seen one before, here’s…

Replaced the clasp on my Spirit Zulu Time

I have to open by saying that I absolutely love the Longines Spirit Zulu Time. It’s one of those watches where everything came together just right. The font of the applied numerals and on the bezel insert, the dial accents and printing, the applied elements on the dial, the style of the crystal, just everything.

But the one thing that I really didn’t like about the Spirit Zulu time was the clasp. I didn’t like the LONGINES text across the length of the clasp, I thought the clasp was very…

Sweep comparison: Spring Drive vs. Precisionist

With some frequency I see FB posts where someone will make the claim along the lines of “the Bulova Precisionist has a smooth sweep so what’s the big deal about Spring Drive?”. Of course the people making such comparisons don’t understand how Spring Drive actually works, and they probably don’t know how the Precisionist works either.

Even among those who do understand how Spring Drive works, many may not realize that although the Precisionist sweep looks smooth, it is simulated…

What is your tolerance for inaccuracy? And how to double the accuracy of any watch.

Once, pondering Citizen’s 1 SPY movement, I reflected upon the notion that, assuming you bought such a watch as an adult, you could likely wear it until death, and not have it gain or lose even a full minute – without adjusting the time. That seems a little mind boggling at first.

But then it raises the question, would anybody wear such a watch, and tolerate it being wrong by, say, 45 seconds? That seems unconscionable. For a non-time-lord, someone who isn’t a die hard HAQ fan, maybe it’d…
