Oris bc3 or Sinn 556 a

Both are independent, with unique styling. IIRC the Sinn's use an elabore grade ETA-2824 automatic movement, whereas the Oris uses a Sellita. Both are pretty much the same VFM proposition, so go with what floats your boat as a watch should make you, and not someone else, smile. Personally, I'd go with the Sinn as I prefer pilot style watches but YMMV.

If you are only considering the Oris because it's a "good deal" then it's a pretty easy choice. Sinn.

Both are above averages watches. But I agree with previous poster that Sinn' quality ranks higher. Nothing wrong with Oris tho, if for example you like more its look, then go for it.

I have the Oris BC3 Advanced and it's a great watch. However I will go with the watch that you love, and not the watch with the good deal.

I've had an Oris BC3 for eight years now and it's still one of my favourite watches even though I've "graduated" to higher end stuff.  The build quality is very good but I can't comment on their newer watches.  In the end, you'll have to decide for yourself though.  Don't buy something you don't like just because it's on sale.  Good luck!

If your into the large watch craze that bc3 will fit the bill! I have owned this one in the past, it fits pretty flat on the wrist!
