Depending on how much cash we are talking. It really depends on how much you like the JLC. The GO and Omega are great watches and you have a lot of utility in having both. The 2 to 1 trade always feels tricky. Without knowing on what your collection looks like, on one hand it feels like you are betraying building a collection. On the other hand, the JLC is fantastic example of technical ability that JLC used to present far more often. It is certainly a more interesting watch than the other two, and arguably objectively "better".
