This one was an unexpected purchase, I fell upon it loved it and had to have it. The piece truly is a NOS piece after inspecting with a loupe, few storage marks not much. With Landeron movement, big chunky and squared its that cool era. Never thought about a green dial before. My pics are quickies as I unboxed it. After I remove all the years of finger prints will grab some more pics someday, the dial is twice as nice as the pics, darker, such an old school shade. It will go on a strap now though saving the signed bracelet. Now what to do with it, pop it in storage or what, at some point these should be worn I guess. Just noticed I got jagged edges upon resizing
This is the old Croton from the early 70's. The Landeron 248 is not as common in these as say the 7733. So basically any 70's 7733 would be comparable somewhat for the time period.
You would commonly see Croton Nivada on the dial. Such as Croton Nivada Sea Diver or Croton Nivada Grenchen Sea Diver. Nivada also used Sea Diver on the dials branded under their name only as in the pic below also so did Croton
This piece has the tell tale sign in the manufacture of the dial that distinguish its layout immediately as a Landeron vs. the Valjoux 7000 series. This trait extends back to the 50's Landeron pieces also, its always been there and was never an intention to remove it, was made that way for a purpose and in design of the movement. I'll bet you don't see it unless pointed out
This is a Sea Diver under Nivada
This is an earlier Sea Diver under Croton only
