Se può essere utile, ho un 2531 con seriale 6473297 che "Ranfft" cita come:
Remarks 1964-1967 excenter regulator Kif-Duofix combined settings for escapement wheel family: each 18000A/h without / 21600A/h with excenter regulator 2510/2530: manual, no second 2511/2531: manual, sub second 2522/2532: manual, sweep second 2522C/2532C: manual, sweep second, date 2522P/2532P: auto, sweep second 2522PC/2532PC: auto, sweep second, date
secondo la tabella qui indicata potrebbe essere, compatibilmente, 1968.
