Hello new here but an avid Omega restorer and collector...

Oh boy, what an introduction and what a restoration. Warm welcome. Astonishing how skilled you are, bravo. If you have the time, please post threads of some of your other restorations.

Ha, I include her in the hobby, she has three rolexes (all flea market finds, all circa 1935 boys size with the word Oyster on the dial and not Rolex, the most I paid was 25 dollars as the sellers had no idea), three Omega 30 t 2s and a platinum diamond and sapphire Bulova circa 1926 Art Deco to go with the wedding band.

As far as stuff on the living room table she has allowed me to hang 12 different American clocks and the atmos but they all have to be passed by her decorating eye.

She actually made me a clock room, yes she made it, ripped up the floor, moved the door frame, dry walled and etc herself, then got all the clocks out of the garage and placed them on the shelves.



Three clocks in the living room!

Firstly, never, NEVER am I allowed to run all 30 clocks. Only one with a Westminster chime, the Atmos because it is silent and a carriage clock repeater in the den.

More interesting stuff about the Omega Checker.

Witschi, the manufacturer sent me a PDF of the manual gratis! Wow, nice service 33 years after manufacture.

The following is my seamaster Running on the mechanical acoustic sensor. Good rate of course this does not do positional error except face up and face down:



And here is an analog quartz watch by Ricoh. To see what it does go to my YouTube video:


The Ricoh on the checker with quartz analog selected:



Notice the seconds per month is lit as is the signal led. The next photo shows another green led lit. Turns out that if the checker cannot sense capacitance then it switches to stepping motor signal. The two green LEDs indicates the stepping motor cycling.



The checker has a built in oven which heats a quartz 32kHz. The rate of the crystal is measured against the rate of the watch whether it is tuning fork, capacitance or magnetic. Then will check the stepping motor against the rate. The ICs on the PCA contain ROM chips coded to calculate the rate in comparison to the tuning fork and quartz or stepping motor rate.

Therefore this checker can check almost any vibration and calculate the rate in seconds per day or month. Also reading the manual the rate can be determined by measurement by means of current drain!

Wow

Dan here, Seiko nut from thewatchsite.com. Geoff posted this over there and my first comment was WOW, and to get an account ASAP at Omega Forums as they will eat this up for breakfast and ask for a double extra serving. We are lucky to have guys like Geoff adding to our to nerdy and obsessive communities. So looking forward to the video!

Imeasure, absolutely right, he sent me over here! You can thank him ;-)

Corrected due to IPad correction errors...

Good to see they have also sorted you out regarding the manual.

They make some of the best watch testing equipment out there. Great company.

Considering the age of this one and what it does I am amazed. The right hand pad with the mirror has a multitude of functions and testing ability such as coil testing and circuit testing as well as the standard battery test but with three typical loads that can be temporarily selected.

More to follow!

As my name implies I measure stuff. One of my clients is Boeing and I did a bunch of work on the 787 control surface manufacturing (flaperons, ailerons etc) which are all made here in Australia.

Currently I get to Melbourne and Brisbane on the 787. On the 777 Sidney was my favourite destination from home here in Vancouver. Where abouts are you.

The importance of a manual:

page 6 describes the line power and the 220v versus 120 volt selector which require a different fuse in the fuse holder. The fuse requirement was also stamped on the back. Since the checker was from Europe it was selected to 220v with the 220 volt required fuse. I switched the power to 120 and swapped the fuse. I did this from the case back prior to getting the manual.

The cord had a two prong European plug which accepted a North American adapter. I did not pay attention to the plug as the machine was working.

Well on page 6 it states

“The Q-test 4100 must be connected to a line socket with earth contact. A connection without earth contact may cause trouble by electric interferences.”

So I took another look at the plug:



Yes, the earth contact had been cut and filed flush with the base of the plug; ie. no earth contact! I did not even notice this even though it is now blindingly obvious!

Of course that is the reason my adapter worked:



So off to the hardware store to rewire the cord with a three pronged North American plug. I initially wanted to keep this cord original until I found out that it had been modified!
