I strarted my watch collection after seing a friend with an skx. And therefore bought a skx013 sold it thought it was to small and settled for an skx 0013, after that i was hooked and bougt and sold watches after i ended up geting bored with them. Now im pretty satisfied. Would you change anything? Im little disapointed on the 50 m only on the hamy but I think its a beuty.
Like others have mentioned, just mixing in different straps to fit your mood will go a long ways. You certainly don’t “need” anything else, but I am partial to GMTs while traveling.
