HISTORY
The Cal.135 beats at 18,000 bpm, has 19 jewels and is 5 mm high. Its size of 30 mm (13") is significant only in that it was the maximum size allowed for movements in the observatory competitions for the wristwatch category (30 mm diameter). This is why there were so many 13"' movements and very few 14"' and 15"' movements.
Any movement larger than 13"' had to be entered in the pocket watch category and had to compete against movements up to 50 mm in diameter. Since larger movements are more accurate, all other things being equal, the chances of a 14"' movement doing well in this category were slim. The height was also limited to 5 mm. Circular movements reached this limit at 30mm in diameter and thus represented the most frequently presented caliber type.
