The MK IIb Reference 072/001 was introduced around the year 1964. Due to the missing date in the caseback, this is just an estimate. The biggest difference to the MKIIa is the use of a lollipop chrono second hand on later examples and the thin sub dial hands, compared to the arrow ones of former executions.

The inner tachy scale of the MK II is found in white and grey and allways with the word “Tachymetre” and starting at 300.


In the range of the MK IIb you just can find the all black dial variation and the one in black and silver. The Enicar logo is still the small one, above the word Enicar. The lume on the dial is made of Tritium.


Minute and hour hand are formed like paddles. They are not painted and have a tip at the end. The tips are not painted too. We see the longer and shorter tips on this reference. Same is with the chronosecond hand which we see as lollipop, but also as straight red hand like on the MK IIa.

The subdial hands are allways thin ones, the arrow shape we don’t find anymore.


The MK IIb has one of the older, thin compressor crowns, but with Saturn on it. They are smaller than the ones of the later references.

The back shows the seapearl logo. This you just will find on the MK IIa and MK IIb reference.
