Oh I thought yours was the second one at STS, did it go to someone here ? It's not necessarily a bad thing to be able to move on pieces...except if you end up missing them ;-)
No longer mine...can't believe some of the pieces i have moved on......doh!

Absolutely love it - didn't even know such a thing existed..... damn you. Now I *need* one.
Hi
Never seen one like it a real beauty
Thanks all
There weren't very many of these made, this example is now on display at STS who have another one. The down side is the last one I saw for sale sold for over £3000!
Great pieces of kit though and something really quite special in terms of what it represents! Accurate to 1SPM in varying temps and if kept at consistent temp apparently 4 seconds per YEAR!
That's a ton of money ! There was that one on eBay a couple of years ago : http://cgi.ebay.com/260796364833 with an asking price of €3K, did it sell eventually or was it another one?
They supposedly produced 1000 of the Calibre 1390 movements used in that clock but they come so rarely that it's possible there weren't as many clocks built.
Oh, did you see my question about the trimmer above? That screw seems like a good candidate but it doesn't seem to be very effective on mine...

An update on the trimmer action and indeed that's the "screw" I pointed to above. Unlike most trimmers I've seen though, especially those on the 151x movements, it's very "subtle", i.e. it will take a lot of turning for the impact to be felt, which is not a bad thing actually. Looking at my notes, it seems that 1/4 turn to the right will only slow it down by about 10 spy.
My testing is slow as I use the "video method" (frame by frame comparisons with a clock on my PC NTP synced and showing 1/1000th of a second) and one week between measures is needed for some good accuracy...if anyone has or has seen a spare Omega Deltatest please let me know!
That's a cracker! Why do I click on topics that just torment me. Just one visit to TZ-UK and I'm guilty of all 7 Deadly Sins :o(

My family were Omega/Tissot retailers in Rosebank, Johannesburg for 35 years and I thereby acquired one of these clocks which were made available by the importers to retailers. It is the grey case model with silver dial. It sat in storage for many years and VERY unfortunately there was battery acid leakage on some of the terminals where the batteries are mounted although the batteries had long since been removed. In fact, one of the terminals was eaten away by corrosion. Anyway to cut a long story short, I was determined to get the clock working again and managed to find a watchmaker prepared to give it some attention. The corrosion seems to have been confined to the battery storage area and fortunately not to the rest of the clock which is pristine. He first detected a bad connection to the electronic board (probably caused by the battery leakage) but advises me that he has surmounted this and the clock has started working but stops after about two hours or so. He suspects that there is some impediment in the drive train causing this which he needs to clear, so I am very hopeful that the clock will again work yielding this reputed accuracy of 12 seconds per year! Clearly, anybody who is fortunate enough to obtain one of these clocks should be particularly mindful of battery leakage and I wondered if there are any 1.5V batteries that are guaranteed not to leak. Leakage can be so devastating. I suppose parts for these clocks are now unobtainable (I was thinking of replacing the entire battery holder section which has been damaged by the leakage). My e-mail is lecolle@mweb.co.za. RAY
Welcome to the forums and great story/quest! It doesn't sound like stopping after two hours would be an electronic problem so hopefully it can be sorted.
Are you saying there was some sort of leak without any batteries installed?
Oh and pictures of yours would be great ;-)
