I know I'll probably get strangled for this one, but apart from the usual suspects you guys already mentioned, I'd like to add Invicta to the mix, specifically their Pro Diver line. Yes, I know, it's a sub-ripoff, but then again, Invicta isn't exactly subtle in its branding.
As said, value depends on taste, but if you like divers and can get over the similarities to the Sub, the stigma of the brand and the weak tritium, it's one heck of a bargain: Mine costs 69€ on amazon, has a hackable, windable movement with a custom rotor and a screw-down crown.
And it runs at - 7s/day.
Just be prepared for some QC issues, just as with Vostok.
