I've done quite a bit of exploration into trying to analyze rate data using fast fourier transforms.Īttached is a pdf of a timing run where I let my Hamilton 992 run from a full wind for over 38 hours. I decided to get a Micoset later to be able to do long rate timing and be able to save the rate data to my computer. I purchased the Timegrapher initially and have it set up next to my work area for quick checks. I have both a Timegrapher MTG-1000 and a Microset 3. The 1000 would be fine, the display is small but uses the same microphone and has the same range of functions, I just preferred the larger screen this has and separate buttons for the functions and no plug pack, by the way the power switch on this machine is a real power switch, it actually turns the machine off, not on standby, same for the plug pack machines, the power switch is in the power lead to the pack.

The machine has already paid for itself in the 5 weeks I have had it, certainly a lot easier and simpler to use compared to the microset timer, because it works much like the B200 with the added feature of the amplitude, never bothered to buy a gradoscope but have used them in service departments that I worked in for a while.

It works well, the lift angle only affects the reading of the amplitude, one of the vibrograf books that came with the B200 shows a lot of lift angles for various movements, not so much for vintage stuff however, that being said you can compare the amplitude by sight and what it says on the timer and adjust the lift angle to get the reading to more or less match.īuild quality is quite good, the microphone is not bad, doesn't have the same free range that I am used to on the B200 because the cable moves with the head, this mic is more complex than the old B200's, it has a small preamp board inside where the vibrograf's is just a simple crystal pickup.īasically you place a watch on the clamp, it takes a couple of moments to figure out the train count then starts showing the rate. I bought the 5000, cost me US$680, colour screen, the power supply is internal so no plug pack, multivoltage 50/60Hz. The 1000 has 4 buttons to control all the functions, you have to scroll through the menu to change and set the options, the 20 have a separate button for each function. Yes my aging B200 motor stopped spinning some weeks back, no one here left here to fix it so needed a new machine, I did have a look at the 1000, 20, these are all newer machines, other older machines will only time trains from 18000, 19800, 21600, 25200, 2880, nothing else so that old english pocket watch with a 16200 train cannot be timed. It dealt with checking the angle of the balance wheel that was involved in moving the fork between its end positions.

I have not seen any tables or similar but I read somewhere a brief description on how to determine the lift angle. Do a search and you should be able to find some further information. Lift angle has been the subject of discussion in another thread here on the forum.

But I understand this comes with being an owner of one of these timing devices. The only problem I have with the machine is that I get so much more information about the behavior of the movement and watches I considered running very nicely actually are way off in beat error and accuracy.

I have compared with my friend's USD3000:- pro machine and I see no need for to pay the additional money for my use. Now, I have not had any other machines to compare with but as an advanced hobby watchmaker this machine is a very good for my needs and very price worthy! I have one of these Timegrapher 1000 and I am very satisfied.
