The A. Myers Collection is frequently cited in horological literature and auction catalogues as the most famous and largest private collection of IWC Jones calibers. The Jones caliber movements are now highly prized by collectors for their historical significance and unique engineering.

The A. Myers Collection is notable for several reasons:

Depth and Breadth:

It includes examples of nearly all the quality levels designated by Jones, typically labeled B, D, E, H, R, and S.

Rarity:
Many pieces in the collection are considered IWC rarities, such as extremely early serial numbers or rare configurations like the Type C (of which only a handful are known to survive).

Historical Reference: 

Objects from this collection are often used as reference pieces in scholarly works, including the definitive book F.A. Jones – His Life, Legacy and Watches by Seyffer, König and Myers.
