I was hoping TG24 would chime in. Glad you did friend.
Glad I could help .The Core is a beautiful watch, the all black one is the prettiest, but the one with the regular display has better readability (as expected). The Core does not use spring bars, the strap is attached to the watch with a spring bar look-alike bar, that has screws on each side, and when you unscrew them, you'll notice that the bar is actually made of two pieces that screw together. I can't explain it really well, I will try to take some pics and post them here.I can say that the standard watch strap it comes with is very comfortable, I just wanted NATO adaptors for it, in case the original strap breaks and a replacement strap might not be available anymore by then.
Always happy to see you post. I feel our hobbies tend to fluctuate over time. My MT hobby is all but over for the most part. While I will use them everyday my collection has remained stagnant. I no longer go to the flea market to hunt them and when I do see them I tend to pass them up. I've been more into traditional folder as of late. Guitars, watches both sound fun to me. All my best to you and your family.
