Are you saying 2 or two brands. If it is the latter I suspect many of us are interested in that. At least I am.

Tony, For the eccentric minority who like to use mechanical, non electronic time pieces, I have details on 2 affordable (under $100), automatic, modern build watches with regular, chronometer type going rates. Please use private email and I can send more details.

More so - in the field of Emergency Navigation. I'm modelling a replacement handle - a grip rather - for my sextant. This grip is thought to be a thick roundish plastic board (approx the size of ping-pong bat) with holes for all five fingers separated around the central area, where a split-system stop-watch (mechanical, of course!) will sit - face to the palm. An index finger will be aligned at the split/resume button. I intend to do it like this: -- with some reference watch I am to start the stop-watch at a full minute of UTC; -- to write down that time in a log-book; -- to shoot a sight and press the split/resume button freesing one of the stop-watch arms - to be able to write down the stop-watch readings without any hurry - along with the sextant's reading; -- having the angle and time interval readings properly recorded - to press the split/resume button again (preparing the stop-watch for the next sight) and proceed with the sighting as described in the previous step; -- when finished with all the sights - to use the reference watch to stop the stop-watch on some full minute of UTC; -- to write down that reference watch readings; -- to use the recorded stop-watch intervals to place the sextant readings on the UTC time-scale accordingly. I guess this is how it is/was done by serious navigators. The only question remains - where a techophobe gets a reliable mechanical "reference watch" (for little money, I mean)? :) Regards, Tony [plain text auto-generated] ---------------------------------------------------------------- NavList message boards and member settings: http://fer3.com/NavList Members may optionally receive posts by email.
