Note: Nathan,

In the Waltham run of #10539601-10540000 I have
two marked as "Premier" 10539948 and this recently
bought 10539781. I attached an ad from NAWCC
showing Waltham's release of the 5 position
adjusted '92 Premier in Oct. 1905. My previously
posted 11527010 (and some others) come up as
"PREMIER" though not marked as "Premier". If you
look at Waltham's 1902 ad in the case portion of
my post you can see their illustration of the
movement shows it labeled as PREMIER and adjusted
to 5 positions. My 11527010 posted still has it's
watch paper showing it adjusted to only 3
positions. All in all it gets very confusing! LOL
Curator Response: Thanks for the report. These are a bit tricky since Waltham combined similar consecutive runs in the factory serial lists. The "Premiere" was adjusted to five positions while the standard was only adjusted to three. Hopefully, we can gain more insight into how these runs were produced. Thanks for posting the wonderful images.
