In 1910, the Lincoln Watch & Jewelry Co. introduced the patented “Landis Automatic Regulator” on its “Landis Watch Co.” watches.
These movements can be identified by the unique regulator spring, differing from the standard “U” shaped regulator spring implemented on other Illinois movements during this period.
The only surviving example observed to date is from the last run of “Landis Watch Co.” movements, Grade 174 [2237901-2238300]. This run is also distinguished from other runs because the movements are simply marked “Landis Watch Co. – Chicago, U.S.A.” without the inclusion of a military-associated name.
