Gruen Master

The caliber 98 is a 15 or 17-jewel movement and is 9-3/4 ligne or 21.99mm in diameter (1926 Standardized Parts, page 22). According to the later Material Catalog 539 two other variants exist, caliber 99 with 15-jewels but different setting gear and caliber 997 a 17-jewel variant of this movement. This later information shows caliber 98 only as a 15-jewel implying the 17-jewel variant changed to caliber 997 at some point. Production start was about 1915.
