im looking to purchase this seamaster 120 , from the information I have from the seller he assures he it's all original there's no servise history the movmet is 599 is this worth pursuing. Sorry for the poor quality of photos this is all I was given .
Thanks

 

Movement looks a bit small.

One below sold a few years ago

Standy, That was one of my concerns but was a bit unsure given the seller has told me its a 599 movement .

 

I don't think cal 599 exists and the number of that movement certainly doesn't read 599. It's too low res to read but it looks like -61 to me, not sure of the first digit.

It's supposedly a chronometer movement based on the adjustment engraving but the only chronometer movements ending in 1 are 331, 551 and 561 and it's none of those.

 

It looks like the movment is a 681 the seller is telling me .. I'm beginning to fonder is this is a make shift seamaster ?
Thank you for all you help

Thank you for clearing this up for me . I take it the 565 as the more disirible movment as I've never seen a 120 with 681 movment before ?

 

It would be, yes. Ladies watches generally don't have the same level of interest as mens watches.

 

Thank for clearing that up ...the seller never made me aware it was a ladies watch. Hence the price . Again thank for all you help ... The search continues .

 

Nice touch from the seller not to mention that it is the ladies size!

Happens all the time with these, you aren't the first and you certainly won't be the last!

A little tricky to assertain from the front on pictures for the inexperienced but a quick tell is the crown size.

Good luck with your hunt, they are a great watch and at the moment still a comparative bargain.

 

I can only but thank you for the good advice, seller never mentioned in his add the it was a ladies watch the hunt goes on .thanks for all the good advice .

Happened to me once with a Zenith. My sister now owns an 18k Zenith

 

Can you also get a 120 fitted with cal. 552?

 

I have a Seamaster 120 model 135.027 no date

Cal 601 hand cranker

Once had a Seamaster 120 model 166.027 with cal 563 also

Traded it with another member toward a Seamaster 300

The 300 has a cal 552 but not sure 120 came with that caliber
