I didnt even know Elgin made bumper watches. Apparently they did not make many because on the serial site it says they only made 40k of them which is the lowest production Elgin Ive ever owned. I bought this not even knowing what it was. The dial is really neat and hard to photograph but the effect in person in sunlight it great. 34mm wide without crown too so pretty large for a 1951 Elgin. The problem was it needed to be demagnetized it was running like 10 minutes fast an hour. Now it running like a minute slow a day. Definitly getting this one serviced and also getting rid of the band on it and putting it on leather strap.
