Omega Polaris Multifunction

Hi, new member here, been wearing a manual wind square Omega from the 60s for ages, but decided I fancied something quartz. I picked up a nice Polaris Multifunction with Seahorse logo and serial number on the back and plain steel bracelet. I was so pleased with it I bought a second one, this time the bracelet having steel/gold links. I've been over both with a loupe, does anyone see anything suspicious? The second one mentioned has Ω Omega Seamaster etched on the caseback but no Seahorse or serial number. I'm prompted to post as I just saw a post of a falsified vintage Omega mechanical watch. I didn't realise they were doing this.
The steel/gold bracelet feels different to the steel bracelet, somehow warmer I was wondering if it's titanium. It appears to be a fraction thinner and lighter.
It could just be they're from different years, the font on the dial is ever so slightly different too. Any advice greatly appreciated. Lloyd

These watches were never copied AFIK so no worries there. The Polaris came in a variety of versions though Steel+Gold inlays, Titanium+Gold inlays even Gold with Titanium inlays. It's hard to tell from your pictures but Ti would be a bit darker and more mate than steel. Got a picture of the casebacks ?

Thanks for the info, I'm really enjoying the watches. You can't see the seroal number on the top one but it dates the watch to 1991. Would the non Seahorse one have the reference number inside?

Thanks, I think the size of these watches and the surprising quality heft (in steel), not to mention the unique gold inlay make these watches something special. A future classic I reckon.

Yes I was wondering if Titane would be written in the back. Not sure why the caseback is different but I see no cause for concern. Enjoy your watches !

I have 5 of these Polaris spread across various models. All case sizes apart from the large multifunction and the two mechanicals but these don't come around too often.

Interesting mention on these on the following podcast around the 12 minute mark:

Indeed, at 13'15" actually but they don't mention the solid gold with Ti inlays ;-)

Thanks for that, it is an ingenios construction for sure. I'm loving the GMT function as I'm traveling at present.

How about these I saw at the museum

Does anyone know where I can find the instruction manual on line please. I can't work out how to use the digital display and sync the hands to the digital display.
