Service history matters at 80+ years. A 3525 that has been serviced periodically is in better mechanical shape than one that has not, but heavy service can also mean replaced mainsprings, replaced chrono coupling parts, and in some cases replaced movement components. Known service history from a reputable vintage Rolex watchmaker adds value.

~~== Still open ==~~

~~~~

~~=== Production total ===~~

No factory production figure is published. The low-end estimate of ~200 steel examples, which circulated in earlier dealer literature, is not consistent with the surviving population observed in the Alpha Hands case-number project. A working estimate of 2,000–2,500 total across all metals is plausible but not archivally confirmed.

~~~~

~~=== POW delivery census ===~~

No full list of Rolex watches delivered to POWs survives in public. The Nutting, Brownlee and Dickins examples are documented; other named-POW examples circulate in the market; but the total number of 3525s delivered to prison camps, versus the number delivered to officers who happened to be POWs but where the Wilsdorf-credit program was not the mechanism, is not published. Rolex’s internal archives on the program have not been opened.

~~~~

~~=== Nutting watch delivery date ===~~

The Antiquorum 2007 lot text reads “sold gratis on 8 July 1943.” Rolex Magazine’s account reads “delivered to Stalag Luft III on 4 August 1943.” Both dates appear to be real events in the shipping-and-delivery chain; the specific reconciliation has not been documented in public.
