Ive just put a nato strap on my electric blue as I don't like metal bracelets on watches and always replace them but on this occasion I'm not sure if the bracelet looks better

 

No such thing as better or worse in these things just different. Think of it as accessorising and wear different options depending on what else you are wearing, the occasion, etc.etc.
I change mine regularly on different watches. Freshens things up and gives different perspective.
It's easy enough to change over any time you need to

 

I, like you, generally prefer straps over metal bracelets and regularly set aside my bracelets to wear my watches with leather NATO straps.

Try a honey colored leather NATO strap on your particular watch and I believe you will find it more to your liking.

NATO Rocks...

 

I’d say bracelet for your particular Seamaster, but nothing wrong with changing it up a bit.

 

Replace the "or" with an "and" and you have my answer ; )
Both options are very different and both are looking great. If you don't like bracelets but a little bit of change here and there, check a rubber strap. Imho Tropic straps do look nice on divers!

 

Ive just been told my nato is fake. I couldn't get from boutique as sold out so got from ebay and its a very good fake. Il get money back and get the leather nato from omega instead

 

That sucks, but thankfully you caught it. Can you post a picture of the front and back of the clasp?

 

Ive just bought the leather nato from omega boutique so know that will be genuine. It is blue , red and grey as not great light at mo. I genuinely can't tell if its a fake. Only one person has said it is out of all people who have viewed pics but if you enlarge mine compared to the commander nato on omega website, the omega lines are straighter

 

Omega boutique has just called and said the 20mm leather nato is actually 22mm but they have found a 19mm golden brown nato that I can have or I can wait until more are in stock as they are sold out allover UK. Its crazy as its just a watch strap lol

 

Wow. Up until now at least, spotting a fake Omega NATO has been really easy. On closer inspection, I think you're right: the alignment of the red threads in the fake strap is a subtle tell. Comparing it to the real one in this A Blog to Watch Article, the difference becomes a little more obvious. The red threads in the fake strap are always in groups of two as the red strip moves along the strap. The real one has a repeating pattern of 1, then 2, then 1, then 3 red treads.

 

I found a real one online and the numbers on the buckle and clasp are different than the one I have. It’s a very good fake but still a fake so no good to me. I’ve ordered a leather nato from the omega boutique and will get Saturday. It’s 19mm as 20mm we’re sold out but can live with that.

 

Put my omega leather nato on now and very happy

 

It depends on your outfit and the activity you are going to do , If you are going for a walk or to the beach the nato would look better but if you are working in an office enviroment the bracelet would look way better with a semi formal outfit.

 

Nice nato strap. I recently got that same one from a member here for my vintage 168.035.
