    Hello to all and to you in particular Geoffrey,

    During in the past 35+ years I have been using the same Omega SpeedMaster (mechanical) watch. When I was doing CelNav on a very regular basis in the French Navy in the mid-seventies, my watch daily drift could stay between 3 to 5 seconds for weeks in a row, which would be "horrific" nowadays for a quartz watch, but was a quite respectable performance for a 100% mechanical watch then.

    The Navy Timekeepers drift requirements then were to stay below 5 seconds a day, otherwise failing Timekeepers were to be sent for overhaul. We generally had 3 Timekeepers on board with at least one of them always showing a drift between 5 and 10 seconds per week.

    They now have quartz Timekeepers.

    Best Regards to all

    Kermit
