I acquired this Speedmaster Professional with sapphire back a while ago and upgraded it recently with a Omega strap and folding clasp. Of course, the solid back version is closer to the orginal but i found it a pity not to show such a nice movement - hence the display back version.
Of course you all have seen the Speedmaster many times over...but i think one never gets tired of it.

in fact it is this model with the display back that I would be interested in when I finally (and I will as the force is strong with this one..!!) get one....like you I want to be able to see the movement.
Few questions - is the sapphire front a dome shape like the Hesalite..?? And does it have the Omega logo inscribed in the centre of the glass on the front..??
Yours,
Andy.
all you've got to do is let me know when and i'll be up.

I thought the display mack model with the higher finishing on the movement and metal brake came with a saphire front too..!!
I would prefere the hesalite front with a display back but didn't think it was possible without buying the regular model and adding a display back. Will have to have words with my dealer..!!
Great pic of the logo too...
Yours,
Andy.
the speedy movement is good enough that it deserves to be shown off. the finishing is better on the OEM 863/1863 display back models, but regardless of that, the movement should be seen.
i would encourage anyone who has a speedy to get a display back for it so you can chop and change as you wish.
here's my 321 calibre with aftermarket display back.

to be honest, i wish i could find someone to make aftermarket display backs for some of the vintage handwind movements like the 286.
