Time to park the Speedmaster after a 17 day trial (18 seconds fast, so pretty good I’d say), and to continue the long term test on my Rolex Oyster Date-Just which I have worn continually since March 11 (94 days, 57 seconds fast, also pretty good). So today I will don my mid-50s Gruen Precision self winder with a German made Durowe, 23-jewel movement in it. Durowe was bought by U S Time (Timex) in the late 1950s because Timex wanted into the battery watch business, and Durowe was making an excellent battery watch at that time. Better than Hamilton IMO. Early Timex Electrics were marked TIMEX, but the movement was a Durowe model.
