There are many MBK interpretations of this watch, and that, coupled to the Chinese clone versions, can cause a LOT of confusion. I always wanted to make a Nautilus guide but I myself honestly have no idea what's going on. You have several different types of crown length and styles, and also different types of datewheels... it is a mess. Anyone thinking of getting an MBK Nautilus should really be aware that there are a LOT of different versions. There is also a very rare version available somewhere that has the correct "dot" layout as per the gen...
Narikaa version:
(In my opinion the best as it has the vintage-style crown, breathtaking smoky blue face, and eye-catching details)
