After a few months with the 300 Heritage I wanted to share my thoughts. Not a small watch with a lug to lug around 48mm and a 41mm case, but in line with other medium-ish divers. Thanks to the homage we lose the helium valve, and with this updated model gain a sandwich dial, lollipop seconds hand, and improved end link connection. Both COSC and METAs certified, this is example is running about 2 seconds a day. Really a great watch with a very comfortable bracelet and a bit of a sleeper on the wrist. Feel free to ask any questions, I try to respond to everyone. Hope this helps!
