1908 Waltham pocket watch is a two-part process: it has a base monetary value as a high-quality timepiece and a significant historical premium due to its unique heroic provenance.
1. Market Value as a Timepiece

* Jewel Count: The 17-jewel movement was a professional standard of the era, making it more desirable than more common 7-jewel entry models.
* Functionality: Being in "running condition" is critical; a working movement can double the value compared to one sold "as-is" for parts.
2. The Historical "Hero" Premium
* Documented Heroism: The detailed inscription presented to Robert B. Roos by friends commemorating the rescue of "Miss Paul & Miss Holt" in Port Hope August 14, 1913, transforms this from a standard watch into a historic artifact. For a local historian or a descendant of those involved, this provenance could double or even triple the typical market value.
