Just bought this Riverside today, it is a 19j marked adjust to 5 positions, Mdl 1908, ser # 22201329. This watch is pendant set, so the question is, I beleive there was about 4000 of them made, but is there any record of the L/S or P/S numbers within that group ?
Thanks for any info,
Bill

sorry all, I just found a recent post about these watches and it basically answered all the questions.
