Hi guys,

as I am not so into Constellations I would kindly ask you for your help. I was offered a arrowhead constellation without pictures of the movement or information on the cal. I am not sure whether it is a bumper cal 354 or cal 505.

Is it possible to check it from the lugs or is there something else I can rely on. Help very appreciated

Two very different movements. You should be able to tell by the way the rotor feels when moving if it's a bumper of a full-rotor automatic. Also, the casebacks are different; google images and learn to tell the difference.

 

Photos of case back and higher quality photos? It looks nice so far.

 

As the watch is not with me I can't test the bumper. Not sure about the difference in the caseback. What do you mean?

 

With a bumper movement, you’ll be able to feel the thumping as the hammer rotor hits the spring whereas you won’t feel the thump in a cal 505 because it is a full rotor.

 

if you don't mind, how much is the asking price?
Looks like a waffle dial to me.

 

Can anybody help me identifying the movement from those pics?
Price is not that cheap - about USD 1.900,-

 

Hmmm, it seems my Xray glasses don't work on internet pictures, only in person. Sorry!

 

Thats a really nice looking one

 

I've just had a look at a few Connie's both 505 and 354 and from the case back straight on view I can't see any discernable difference. From side on the cases housing the 354 appear slightly slimmer ( I haven't measured them )

But from the dial style with the applied 'Omega' and the later 'Ω' my money is on a 505 ref 2852

 

It's a very nice waffle dialed ref. 2852

 

Thanks to everybody for your help

@ConElPueblo can you please let me know what the difference in the caseback is as you mentioned before. Would be nice to learn something for the future

 

Beautiful. Love.this.arrowheads.

 

I would pay that. Awesome looking watch!
Will he hard to tell cal without a movement pic I guess.

 

I've been googling references like a maniac the last half an hour and now I am not certain anymore
If there were two casebacks next to each other, I could be more certain, but I think I'll just scuttle away again and take back my previous statement - but no matter what it is, it sure does look great

$1,900 would make it a firm "Hell no!" from me, though.

 

Wouldn't you think the thinner lugs are for a 354 (though it could just be the angle...)?

My 2852 for comparison (and they sure look similar in a couple ways)...

 

There are case variations, so not a firm clue. I have a 2852 with skinny lugs and have had a 2852 before with fuller lugs...
