Seamaster/Constellation size comparison

Hi All,

I’m looking to buy a 166.010 Seamaster to change up my collection a bit. I already own dog leg/lyre lug constellations so was hoping someone would be able to share a photo side by side please so I can see how differently they’ll wear

The 166.010 wears a little larger than most of the other non-jumbo 1960s SMs and SMDVs. Not jumbo size, but the shape of the case (i.e. the way it flares out in the middle) just makes it a little bigger, IMO. I could take a photo, but I don't think the difference will really be substantial, and it would depend on the angle of the photo, etc. I do think it will feel slightly larger than a typical 34mm Constellation (e.g. 14383/14393), but not really larger than a 2852. They are still pretty small watches relatively speaking.

If you really want substantially more, you'll need to go to one of the jumbo models.

Awesome response. Thank you. Not looking for it to be substantially bigger. Was hoping it would wear somewhat similar so this is really reassuring 😀

Thanks again!

I also have both and I think the 166.010 wears bigger than the 168.017.

That said, I do have skinny wrists

Thanks for the pics! The c case Connie’s wear compact as they’re quite thin and the lug to lug is short. Wonder how it’ll compare to a dog leg as they have quite a long lug to lug!

I'm a pretty poor photographer but maybe this will help. The Seamaster definitely wears a bit larger. I have 6.75 wrist.

Great pics! Thank you. It actually looks quite slim. I thought it’s be quite thick. Was hoping it would be fairly slim. Despite the case looking bigger it looks like the lug to lug is quite squat?
