The Ocean 2000 had a case completely made of titanium, a metal that was hard to process in those days
One of the demands was to develop a special model that should be completely anti-magnetic
The bezel was black instead of grey, the crystal was flat instead of dome shaped, and the edges of the minute hand were red
The IWC Ocean BUNDS were equipped with basically two different movements: cal. 2250, an ETA cal. 955.412 quartz movement and cal. 375, a mechanical movement based on the ETA 2890 movement
This cal. 375 had a diameter of 28,0 mm
It was further modified and improved to cal.3752, cal. 37521 and
cal. 3755 AM
All these calibres had a diameter of 25.6 mm
The specifications of cal. 2250, quartz are :
·Weight 57 grams
·Quartz movement, 32.768 Hz
3319-01, both developed for combat swimmers, have both been equipped with a cal. 2250 quartz movement
The watches differ in the way the strap end links of both the Titan and the Nylon (Velcro) strap are attached to the watch case
Titan strap and Nylon strap have a different NSN-number
The Case and Crown
All BUNDS have the same grey and ultra-light titanium case
In 1984, few watch manufacturers were able to make a watch with a titanium case, as it was much more difficult to process than steel, gold or even platinum
The unilaterally anti-clockwise turning bezel is black, in contrast to the civil Ocean 2000, where it is always grey titan colour, the same colour as the case
The bezel can be turned if, at the same time, it is pressed downwards at two opposite points
This prevents an unintentional turning of the bezel and as such it increases security
On the bezel at 12 o’clock, a triangle is present loaded with radio-luminescent material
The screwed crown is at a typical 4 o’clock position
The screwed case back has eight holes, symmetrically placed in a circle
On the outside case back the word ‘BUND’ is engraved in capital letters, below that the 13-digit ‘Versorgungsnummer’ has been printed
There is also the 7-digit case number, much less visible than the NSN number
The inside case back shows seven inscriptions, one below the other
Below that again the case number, and finally the 4-digit reference number
A flexible black synthetic ring seals the case
The indices are represented by rhomboid-like markers and contain radio luminescent material
At 12 o’clock, a somewhat smaller triangle than on the bezel, also illuminating, is present
Between 1960 and 1970 the watch industry stopped using the highly radioactive Radium as illuminating material
Tritium produces no gamma rays but beta rays which are so weak that they will not leave the watch, they are simply blocked by the case back and even by the crystal
source was present on board to ‘turn-on’ the zinc sulphide powder that covered the dials of cal 67 K.M
There were two colours, black and grey, and two different lengths 22.3 and 31.0 cm, respectively
These nylon straps were attached to the watch case via two titan attachment links
The titanium bracelets were adjustable to 5mm the size of one link
Ref 3314-01 and ref 3519-01 have a square box made of hard white synthetic material
It measures 10.5x10.5cm an it contains foam with a cut away space to store the watch,
its original square box made of hard white synthetic material,
its original IWC simple 2-pin device that pressed the spring locked pins between the links to adjust the length of the bracelet
its original IWC grey nylon velcro strap attached to the watch case via two original IWC titanium attachment links and
