145.012-68 with an 861 movement

Hi all,

I'm considering buying a Speedmaster 145.012-68, but it has an 861 movement in it. Otherwise, it's all correct looking. Does anyone know if the watch *should* work correctly, i.e. are the 321 and 861 movements interchangeable?

Thanks for your advice and insight,
Conor

Ditto

this seems more likely than modifying the feet of a 321 to fit an 861. what's the movement #?

Thanks all for your inputs.

The movement no. is 30590157.
I haven't seen the back of the dial to check the feet.

Here's the link to the watch: https://www.purcellauctioneers.ie/c...nd-rarities-to-include-allcock-brown-lot-237/

Any other thoughts? Much appreciated.

This reference is expected to have the 861 movement. That’s correct.

i think the caseback must’ve been changed at some point. Watch isn’t a 145012-68 SP. The description “Serial number on inside of rear cover 145012-68 SP. Numbers on workings 30590157” should be understood as ‘Reference number on inside of rear cover is 145012-68 SP. Serial Number typically relates to the movement …. is how I’d understand it


I haven’t followed so not sure the value for a ‘71 speedy. You can check sold listing in the for sale section here, or eBay.

edit - https://speedmaster101.com/serial-quick-reference-to-78/ might be helpful in checking if the movement serial is about right … happy hunting.

Thanks again folks.

According to speedmaster101, the movement number should be from a 145.022-69 (I.e. 2842 xxxx - 3162 xxxx).

So it seems is a 145.022 with incorrect case back. Is that how is seems to you?

Ah OK, got it. I was initially thinking (in the absence of any info on the movement serial number) that it was likely a -68 (given the DON bezel) but the dial and movement had been swapped out. So odd to me that the caseback is the incorrect piece.

Thanks all for your insights.

i guess the auctioneers wanted to cover all the bases and CYA.

Hi All,
Confession time - I bought the above Speedy! I registered after the auction to post here but collected the watch and thought it better to hold off until it had a clean and service.

For info, I'm more of a Rolex guy but have a Speedy Broad Arrow GMT (3581.50.00 from 2006), Speedy X-33 (1st Gen 3290.50.00 c1998) and a Constellation Double Eagle (1519.51.00 from 2006) - I'd been keeping an eye out for a birth-year Speedy and saw this one with a very low estimate but a few obvious issues -caseback ('68 vs. '69+ serial), bracelet and overall condition. I was looking for a daily-beater rather than a museum piece so was happy to pick up a bit of a project but got a bit excited and ended up overbidding to win the lot at €4,500. Auctioneer was surprised at the result and was happy enough to do a deal on the commission side when I collected it from Co. Offaly but still ended up costing €5,000 (+ diesel for the road trip down from Dublin)

To say the watch was in need of a clean was a bit of an understatement - bracelet took 4 trips through the ulstrasonic with an alkaline cleaning agent and I'm still not sure another go or 2 wouldn't be needed!. 1 bracelet pin had rusted in-situ and left some pitting on the case between the lugs and the end-links seemed to have been bent a little bit to fit (see pictures below) but the bracelet itself was in great condition for it's age. Seems to have a full set of links with some stretch on 1 set of expanding links but overall is pretty tight and very wearable.

The chronograph reset wasn't working but turned out to be the accumulated cr@p under the pusher rather than anything mechanical.
The watch was actually keeping ok time but would stop after c12 hours from a full wind so went off to the watchmaker for a thorough clean and service.

I picked up the watch yesterday (€350 lighter in the pocket) - watchmaker said the movement was in pretty good condition but hadn't been serviced in a long while and oils etc had degraded. Dismantled, cleaned and re-oiled and back in my hands now running strongly.

Crystal had a light polish revealing Omega logo on the underside and much clearer than before still some surface scratches but he didn't want to get too aggressive.
Bezel is in good-enough shape compared to some DON bezels I've seen - some paint loss but reflects a 50+ year-old watch nicely.
Dial looks to be in good shape with lume on the hour plots aged nicely and pretty clean.
Hands aren't in great shape - there is lume loss on hour/minute/second and lume dust had to be blown from the dial-surface during service. There is also quite a bit of paint loss on the hands but still serviceable as a daily wear.
Crown looks ok but chronograph pushers have some pitting on the stems.
The case itself still looks sharp - not enough of a Speedy guy to rule out a light polish in the past be definitely nothing major - showing nicks etc. commensurate with age and the only major issue was pitting between 1 set of lugs from the rusted bracelet pin. Watchmaker cleaned same but I didn't wan't to go down the refinish / polish route so left them as-is.
Caseback is from a 1968 Speedy and has deep-enough scratches from a ham-fisted attempt to open - auctioneer was a bit evasive on collection so may have been down to him. I prefer the plain hippocampus rather than war-an-peace written casebacks on later versions so will probably keep as-is.

So all in all - in the watch for €5.350 which I suspect isn't the greatest deal ever!. I think there may be some value in the bracelet and end-links and I may move them along in time - watch is on a nato at the moment but I've seen vintage Speedy's look good on chunky brown / black leather straps so may end up going down that route.

Some pictures are attached for your enjoyment - unfortunately I didn't take enough before pictures to accurately reflect absolutely awful state it was in but t hink of a bachelor farmer wearing a watch for 30/40 years without cleaning (himself or the watch) and you'll get the idea 😀

Sorry Guys, last bit reads :
