Thanks for the video. You saved me $160 as I don't now - nor ever will - own an automatic watch! But your channel is great. It's detailed, focused on the affordable watches, and magnificently unpretentious!

I bought one about 6 months ago and love it, you've probably played around with it enough and found out how sensitive positioning of watch is in the different positions (6) and how much change there is in the different positions. I haven't got around to regulating any of my watches yet, my house is a dust bowl and don't want to contaminate the movement.I'll wait til warmer weather and do it in my garage. I couldn't figure out how to place back ing the styrofoam box so I looked for unboxing vid and found you showed me what I needed. Thanks

You should always have the crown held against the metal prong by the spring clip so that the microphone can hear the vibrations/sound better and give the most accurate reading. If the watch mechanism is removed from the case the crown doesn’t have to be in contact, because the metal body will do the same thing.

Weishi No 1900 AliExpress $169.99 USD + $7.57 shipping (at this moment). Color LCD Display 480 x 272 pixels or ~4½" x 1½" Threaded metal inserts for the chassis screws, also for the PCB screws. Microphone assembly has a preamplifier with a piezo vibration element. Back of the PCB has a modern design compared to other watch analyzers I have seen The main CPU is an 8051. All in all not bad.

Mine was DOA which is a shame. I thought it seemed well made, but something internal was dead. Power supply was fine. Back to Amazon it goes.

The "value" key changes the screen contrast when the grapher is on; when the grapher is paused/stopped, you can enter the menu with the "Menu" key, and then you can manually change the bph and the lift angle. [BTW, the instrument does not automatically recognize a 3600 bph beat rate: maybe, if you manually set the bph, you can graph a quartz watch!] Double check §5 and 6 of the manual, there are some interesting things!

Thank you friend for dismember this piece....help me a lot.

Interesting video. I was literally just reading about this exact unit tonight debating on getting one. One article said you need to enter the movements lift angle. Did you have to enter that?

U have talent, pls keep going.

Thank you for a very interesting video. I've been thinking about buying one myself but then I'm afraid I'm going to be consumed with checking and attempting to regulate all my automatic watches.... 🤔 I have to research "amplitude" and "beat error" to understand these parameters better. If you are able it would be great if you could cover in a future video. Enjoy your new timegrapher as it is a great addition to your overall equipment arsenal, and will be fun to see what results you get in future watch reviews. All the best!

If I'm not mistaking these time graphers are only meant to be used on manual wind or automatic watch movements.theres separate testers for quartz watches that are much cheaper then a timegrapher.forget what they're called but buddy of mine has them and helped me determine 2 of my Ronda quartz movements took a dump on me and needed replaced.one was a Ronda 715 and other I believe was the 515 gmt movement.actually should be receiving my replacement Ronda movements in mail in next few days so I can get watches back up and going.fun learning how to fix your own watches and how to service automatics and manual winds and its relaxing.gives you more appreciation for your pieces plus it saves you some money in long run assuming your willing to invest about 7 or $800 for some good tools and oils and have the patience to work on watches.for me its a way of calming the nerves after a work week since ammo is too expensive rite now to go target shooting every weekend.lmao

I'm not an experienced "watch guy", but I didn't THINK a quartz would do anything on a time grapher. But you did me a service by proving that. (Now, if I can just stop myself from buying one of the fool things.) 😬

Thanks for the video. You should regulate your watch. You've got the main tool now... 🙂

10:50 made me want to go postal.....but Th,e Force intervened.

I don't think a Timegrapher is for quartz watches - but even so the instructions said 3600 bph is available in manual mode - not automatic mode. Does it work if you manually set 3600bph?

These are not designed for use with quartz watches even if you manually set the beat rate to 3600. The machine is listening for the noise generated by the pallet fork and balance wheel which don't occur in the quartz. It will pick up what looks like random noise. These machines work to the nearest 1 sec per day which is well outside 99% of quartz watch accuracy anyway. So it's quite futile. A proper quartz tester such as Seiko qt2400 which is their latest costs $10,000 new and can measure to 0.001 sec per day. Trouble is they only sell to authorised dealers.

Nice toy, even if I’m not sure how useful it really is. I use a G-Shock MB6 watch to see how fast or slow my automatics are. If I were to regulate any of the movements I would get one, but as Marc of Long Island said in one of his previous videos I leave that to guys who know what they’re doing.

You need at least 260*

Amplitude isn’t great.
