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…

I’ve read the Citizen A660 manual, but cannot determine whether you have to “reprogram” the perpetual calendar after a battery change. I would assume yes, but thought I’d ask the forum to see what happens after the battery is swapped out (you never know – it might retain the config)…

Hi

I want to dive into checking the rate of my small collection of HAQ (& RC!) watches (& clocks!) and the video method seems to be an accessible way to go. My Google Pixel 6 Pro does 240FPS slo-mo, which is nice, so I’m just looking for a time reference. I’ve seen a few GPS supervised clocks at reasonable (to me) prices:

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…

Hey guys. Here’s a head scratcher.

I just received my brand new vhp gmt a couple days ago. Date was fine, time wasn’t and my phone (2024 model samsung) wasn’t compatible with the app.

So I set the time and second for home manually.

Based on what i’ve read, you can’t go further than one day forward or back on this watch.

I wanted to…

Longines VHP GMT seems date programmable from the app?
