Great video, by the way when nh movements spiked up in price, I literally used to buy invicta watches just for the nh movement. 😂😂

The Invicta had a very low amplitude. It either needs to be serviced or the lift angle was not set right. If it's using a Seiko NH35A movement, the lift angle should be 53°. Another reason for low amplitude is low power

Wonderful video. Lots of information, and adjacent subjects covered.

Thank you so much, always wondered about this.

Great video. My first unit was DOA. Waiting for a replacement.

Great video, thanks.

Seems to be pretty normal readings. What's wrong with those times and beat errors? You watch is fine.

What are those smaller sized 2nd line values in each column? (small white font -2, -4, -1, -2 etc.) The ones below the 1st line, (highlighted, larger font) actual values?

10:15 - Impressive.

I thought the crown should be against the metal part opposite the spring to allow the timegrapher to give the most accurate reading. Or is it different for a pocket watch?

BOUGHT MINE BUT THE DISPLAY ONLY LASTED A FEW WEEKS , ITS VERY FAINT NOW AND HARDLY USEABLE ,

Reminds me of buying a cheap dial thermometer at Walmart. I stood in front of the display and it seemed like every one of the seemingly identical thermometers read a different temperature. LOL

Peter, thank you for this. Very detailed. Couple of questions if you dont mind : 1. Is this Weishi brand ? 2. Any major difference between this 1000 model and 1900 ? Thanks in advance

Hey bud had an issue with the watchmaker I use recently. They regulated for the wrong movement and was running 6 minutes fast every hour. I sent them this. Thoughts if this makes sense? This is what I sent them. “One thing I forgot to add was I believe your watchmaker had regulated the watch at 19800 bph which is the regulation for a 1556 movement and would be great if that was the movement, this is why it was reading as being running perfect on the timographer. My watch has a 1555 movement which is 18000 bph which would be why the watch was running 6 minutes fast every hour. So when you get it back it should read on the timographer 18,000 bph on the machine. That year 1972 was the transition from 1555 to 1556 quickeset date movement so maybe that was the confusion regulating off the year instead of the movement.”

Help please! Bought used tudor black bay 58 m79030n caliber MT5402 Time graph Test period 4s Lift Angle 49 degrees Wind 30 times let it run for 1 hour Then I tested it on timegrapher amplitude was under 250 so I wind it 20 more times then my readings were Dial up +1s/d Amplitude 262° Beat error 0. 3ms Parameters 28800 Vertical crown left -11s/d amplitude 189° bet error 0.3ms Parameters 28800 Vertical crown right -7s/d Amplitude 197° Beat error 0. Oms Parameters 28800 Dial face down -1s/d Amplitude 255° Beat error 0.2ms Parameters 28800 Does the watch need to be repaired? Should I return it? Thank you

On the watch you assembled with the valjoux 7750 either you don't have the lift angle set properly or you added too much/wrong oil to the balance because you're amplitude is too low for a new movement... Unless you didn't fully wind it and let it settle in for about 10 minutes.

A TM without a gain setting can give inaccurate results. Much better with the Weishi 1900 model.

I got one of these for Christmas and I found it to be almost useless. Crazy variations in all the readings even my dialed in Speedmaster. I was careful to know the settings for each of my watches but no consistency nor any accuracy in the output. Really an expensive toy.
