Rare 16S 17-jewel Model '99 Two-tone Waltham in a Display Case

Another great thing about this hobby and the study of railroad-era watches is the occasional variant that you've never seen or heard of before. Waltham's 16-size Model 99 is one such design in which I'd thought I'd seen every known pattern and style, including the interesting two-tone variant with the flashed-gilt train and barrel bridges but with a nickel pillar plate and balance cock. All serial numbers match on this example, which has a flashed-gilt perlaged pillar plate, nickel bridges, and the gilt hardware package found predominantly on the Grade 636, and is a first for me. Other examples within a couple hundred numbers of this one do not have these features.

It's been fully restored for the next owner with a thorough cleaning and a new mainspring, fronting a snow-white Arabic dial behind correct blued hands. It also appears to be an original combination of movement, dial, and a very interesting two-tone display case with nickel covers and a gold-filled frame. The rear cover matches the front one and does not look to be converted, but factory, so there is no visible trademark. Matching lanyard and display stand included.
