That’s what I figured searching for more info re: LGF. But it’s a good talking point if ever. It’s a lovely watch and I like the fact that it’s considered to be a classic now. It’s a joy to look at every now and then.
But as I mentioned I like the 16570 polar better, specially how it is more “tapered” when I wear it on my wrist:

I still have the single clasp bracelet. I just love that both watches have lug holes so I can change straps. It’s one of my joys choosing and pairing straps. But so far, black rubber straps are my favorite. With the polar, the face pops out of my wrist.
