STP 1-11
High confidenceSeeded principally as a dating tool. STP was established by Fossil in the 2010s, so its calibers cannot appear in any watch predating that — which makes an STP movement conclusive evidence of modern production on a brand whose reissues deliberately resemble their 1950s ancestors. That is the most useful thing this caliber does for the catalog.
