Unable to locate what I seek, I'm asking for advice. Because I live aboard a bluewater cruising sailboat, I cannot do without certain complications. For example:
at least Dual time zones - UTC is paramount for navigation and record keeping. Pilot's watches are attractive in that sometimes they simultaneously keep track of the embarkation and the destination time zones, but three time zones is probably unachievable along with everything else. Ideally, UTC would be displayed digitally in six digits (hh:mm:ss) while analog hands displayed local time. A danger exists if UTC can be accidentally mal-adjusted when resetting local time.
Chronometer - For celestial navigation, it is important to keep the error (seconds per month) minimal, but what is more important that any UTC error be entirely predictable. Each erroneous second produces a calculated position error of approximately 1/2 mile. So, on a month long passage from say Sand Diego to Hawaii, taking two or three sights per day, the accumulated error can be sizable and worrisome.
Stop Watch - Essential for accurately measuring the flashing intervals of lighted navigational buoys, for example.
Self-Powered - Batteries are not necessarily available or reliable in the remote islands of the Indian Ocean, South Pacific or South America.
Vibrating Alarm - Audible alarms are often undesirable because of possible conflicts with shipboard electronics, waking the off-watch, and can be drowned out by the noise of crashing waves.
Waterproof - Preferably equivalent to a minimalist divers watch.
The closest thing I've found is the "Dakota REQ Vibe" (https://dakota.webfeatsecurity.com/c....aspx?ProdID=9) but I've never heard of the manufacturer, wonder about accuracy, and, the funky external charger is less appealing than an ECO-drive, Kinetic, or other self powering mechanism.
Thanks in advance for what wisdom can you offer?????????
