The case of the Flying Regulator Night and Day is the same as the Open Gear version, meaning a 41mm case in polished and brushed steel, with the signature knurled bezel and onion crown. The lugs are rather straight and long, thus this watch requires a solid wrist to feel comfortable. The 5-link steel bracelet is nicely executed and brings a more casual style to this watch. 🇨🇭 ♢ #chronoswiss #regulateyourtime
