One with pale grey dial and leather strap, the second with slate grey dial and original integrated steel bracelet (notice that chronometre is printed on the dial, wich is not common). Both with me since 15 years Wich one do you prefer? Have a Nice day, a watch day! Franck
Hi, I like very much this combo: 1550SG on an Heaton unlined shell cordovan bund strap color number 8. Not too macho, perfect size for this big chrono and very very confortable ! Have a nice day, a watch day! Franck
