Nato Strap confusion

I apologize in advance for a most likely repeated question. I just purchased the seamaster diver 300m (ref 210.32.42.20.01.003). Along with it I purchased two omega polyamide nato straps thru the boutique and they ordered them for me online.

My question is- which spring bars should I use for the most secure robust nato straps setup? I know it is probably a stupid question but I’ve been seeing a lot of confusing answers online. What I mean is : curved or straight- some people get both when buying an omega strap some don’t. Some say a certain brand some say another. Some say natos are bad and cause issues some say they’re the safest.

The reason I’m asking is I plan on using the watch in pretty rough conditions and it definitely has a high chance of getting knocked around and dinged. I’m just making sure I have the best info so the watch is most secured .

Any info would help thank you

The only time you need curved springbars for a NATO strap is if your strap won't pass through with a straight springbar.

Some people think the notches on a standard springbar can catch on the strap and compress and come undone. Personally, I've never experienced this and think it's much ado about nothing. That said, I don't wear a NATO very often.

If you plan to wear the watch exclusively on a NATO, you could use shoulderless springbars. These are the springbars that have no notch for a springbar tool to compress them. The ones that would be used on a watch with lug holes. This would eliminate the possibility of the springbar compressing unexpectly. However, in order to remove the springbars you have to cut them in half to remove them. Not ideal and certainly not a great option if you would want to switch back and forth from NATO to bracelet.

If it were me, I'd just get standard straight springbars of the proper length and move on with life.
