I am delighted to add a Vintage Citizen Crystron 150m Diver to my collection. I used to own its bigger brother the 600m model, and I let it go several year ago and I regretted it ever since. (The main difference between the 600m and the 150m model is the 600m was larger all round and had Mercedes hands.) Click here to view a picture. This Vintage Citizen Crystron 150m diver dates from 1978, rare is a word that is over used in WUS circles but I will say these Crystron diver models from the 1970’s are indeed rare models as they were only released for sale in Japan. Incorporating lovely paddle hands, and applied baton hour markers, some models have round hour markers (see last picture/advert for both models).
The size is quite large for a 1970’s model 41mm excluding the crown, 45mm including, lug to lug size 48mm, lug size 20mm, width 13mm. The watch incorporates the Crystron Quartz movement 7301A as pictured here. I am having some difficulty in finding appropriate information regarding the Crystron models. I know some of them were solar watches, in fact I think the Crystron was Citizen’s first solar cell watches. But this did not include the 150m and 600m diver models. My 150m diver has had the original crystal replaced by the previous owner. It has been replaced with a sapphire crystal and has made photographing the watch quite a challenge as it is very reflective and my camera skills are lacking. But the advances in watch crystals are appreciated as this is much tougher that the original, and as the original crystals are no longer available, it is the right choice.
The watch is shown on here in this cool advertisement priced 45K yen in the 1970’s! That was over double the price of the mechanical equivalent! At the time that was very expensive.
