Working, slightly stiff to wind and was tested over a 16 hour period and gained 3 to 4 minutes. It will need a service to keep absolute perfect time and is sold as is. The gold plated case is 54.5mm in diameter. 1897 Elgin G M Wheeler, Grade 144, Model 3, Class 4, 17J, 18S, lever set, stem wind with date serial number 6770913. Scarce only 41,000 of this model were produced during 1897, you have to wonder how many still exist after 120 years !! Very nice dial & case. Some plate loss to the stem bow.
