Recently arrived and with his permission using some of the sellers pics as my point and shoot (and photography skills!) aren't up to snuff. Not exactly a rare beast, but as I'm trying to amass a representative sample of Omega's 60s and 70s output I had to have a Cal 861 and one of the Speedie 'Marks'so why not go for the first and IMHO coolest?
Introduced in 1969, the Speedmaster II was I understand originally intended to replace the original but wiser heads in sales and marketing must have realised the value of an iconic model associated with man's greatest adventure to date, hence it was only in the line until 1972. I have read elsewhere that Omega even presented the Speedie II to NASA for testing as their offical flight approved watch but were basically told thanks but no thanks, which may also have contributed to the relatively short lifespan.
Design features intended to improve on the practicality of original Speedie Pro were; increased water resistance up to 120m from 60m, bringing the tachymetric scale 'inboard' sandwiched between two layers of flat anti reflective tempered mineral glass and of course marking the 'proper' transition from the Cal 321 to Cal 861.

Developed 22 years apart by the same genius, Albert Piguet of Lemania (who also oversaw the devlopment of the fabled Lemania 5100 by Raoul-Henri Erard), the 321 and 861 represent to me at least the twin pinnalces of Omega's chronograph movements. There are many threads extoling the virtues of both but I think it's interesting that the cal 861 was develpoped to take advantage of the technology available at the time as did the 321 in it's day. The 861 used a flat balance and upped the frequency from 18,000 in the 321 to 21,600 to increase accruacy and reliability, the vertical column wheel controlling the chronograph functions was replaced by a flat cam making it easier (and cheaper) to produce and service and the steel chrono brake lever replaced by one made of Darlon - one of the first instances of using synthetic materials in a chronograph movement. A step down in horological quality it could be argued but the fact that it's remained in production pretty much unchanged since 1968 speaks for itself I think.
The barrel shaped case of the Speedie II was very much of it's time as was the use of grey and orange in the Racing dial. However, unlike a lot of late 60's and 70's desing I think it still manages to look contemporary rather than retro. The case finishing with sunburst bezel, polished bevel and horizontal sides is just lovely but v.expensive to refurbish, so when Jack agreed to sell me his Bienne serviced and restored model (he also sent me the original mint dial and all the parts replaced at service) I was chuffed to bits.
The original 1159 bracelet is extremely comfortable and because of the five facets rather than 3 a lot better looking than the slightly later 1171 (which I've also found to be a bit of a hair puller).

Finances and natural inclinations mean I don't buy often, so acqiuring a watch as well sorted as this one that also ticks so many of my collectors boxes has made me a very happy boy indeed.

When it first arrived I was almost reluctant to wear it as it's so pristine. I've managed to overcome that now but it has been reserved for special occasions (yeah right!)

I've seen several examples of the work of a watchmaker here in the UK who has a lapping machine that can recreate the mix of sunburst, mirror polish, horizontal and vertical graining on may vintage watches of the period including a Speedie II. Several collectors on a watch forum I use have used him and are really astounded with the results. I can't vouch for him personally as a case refinisher but he did an excellent repair job on my Mariner 1.
Drop me a PM if you'd like the watchmakers' details.

Thanks Graham
Nothing in the collection from 1964 so you and your bank acount can rest easy! I think the De Ville chronograph you're referring to is the ref 145.0017 Calibre 930, a development of the Lemania 1872, which was also used in a different layout for the (in my view anyway) hideous and overvalued Bullhead. Top of my wants list at the moment is a blue dialled 176.0001 Cal 1040 Seamaster, and (although out of my self imposed timeframe) a nice steel cased T17 with an Art Deco style dial. However both will have to wait until the coffers are replenished after the purchase of the Speedie II.

thats the one. rare beyond belief although i know where onr is for sale. funds prohibit though. us brits have a hard time dont we :)
the other 2 both nice but very different. i've had them and any T17 is too small to wear and the square 1040 seamaster is a big heavy beast. you have a flightmaster so should have no problem with it.
happy hunting
Graham
