Interesting Elgin convertible grade 47 (show and tell) I started this thread 9/14 after making an interesting discovery. It was quite amazing how loose this movement was in a 16s case. Measuring the movement showed it was indeed a 14s. Thus I knew I needed to find a 14s case that was deep enough to accommodate an Elgin convertible movement. In my collection I have some early 14s Walthams, both hunter cased and open face cased. I decided to try my new Elgin movement in my Waltham cases. The Waltham cases fit the Elgin movement like a glove (minus a lever slot in the right location). I now knew what kind of case I needed. Last week a seller posted an empty 14s open face Waltham case with screw on bezel and screw on back. Once I cut a lever slot in the case my 14s Elgin convertible movement dropped into the Waltham case like it belonged. Here it is. Elgin only had one run (1,000 numbers allocated) for their grade 47 convertible. It is a mixed run with both 7 jewel and 13 jewel movements. #602,423 is the 5th grade 47 in my collection and my 1st 14s Elgin. My collection consists of two 7 jewel and two 13 jewel watches. My 5th grade 47 convertible is the 7 jewel 14 size. These watches have been interesting to collect and examine. I have done a COA on all 5 and all are matching number movements. I would like to point out some interesting aspects about the watches I have. The 13 jewel versions I have seen and recorded are in the higher serial numbers. I thought all matching number movements through at least #602,544 would have pressed gear mainspring barrels, my new 14s movement proved that wrong. The most obvious difference between the 16s and the 14s movement is the proximity of the the top plate and barrel bridge screws to the edge of the movement, most noticeable on the barrel bridge. Here is a 16s 7 jewel and the 14s 7 jewel for comparison. Finding #602,423 raises questions. Why make a "few" 14s movements? How few is a few? Surely this is one scarce Elgin convertible. Did the few 14s movements all have 16s dials originally? As shown in my other thread, it was the 16s dial on the 14s movement as compared to the 16s dial on the 16s movement that caused me to measure the movement.
