Isa 8173 setting instructions

you cannot fix this. Unfortunately for movements to be that exact they cost a lot of money and the movement inside your subaqua is not that high tech and accurate. This is what makes watch really expensive the little things like this. Unless you are buying a 10k watch , they usually are not going to have the top of the line movement . The movement you have in your watch is an ISA 8173 and that is as accurate as the watch will get.

Their web site is pretty useless as far as instructions go (as you may have already found) but looking at their range, it looks like your is a "Trax" model.

As a guess, I suggest that you pull out the crown wheel (it may need rotating anticlockwise about a 1/4 of a turn) and pull is out.

I would expect their to be two "out" positions, the second one usually operates the hands and the date, so this leaves only the first position to be available to adjust the date.

Experiment a little to find the function you need!

I actually have a model 6206 coming to me as I type this. The only difference is the color scheme. As to the power reserve, there is nothing for you to do. It's just shows the approximate amount of battery life left in your watch. If you don't have your manual, leave me a way to contact you and I'll send you the instructions for your alarm when mine arrives. If you don't want your regular email listed on here, I would suggest that you go to yahoo or some other free email site and create an address just for this information. Then you can just not ever use it again if you don't want. I'm new to this site, so I'm not sure if I will automatically get notification if you as for a clarification request or not. I'll do my best to keep watching for your contact info. I hope I love the watch as much as I THINK I will!! :O) ...and I hope you enjoy yours just as much. Best of luck!

Go to www.invictawatch.com and click on 'Collections' and then 'Instruction Manuals' and download the manual. One manual covers all their watches - just find the pages that match your watch.

You have to change the battery. Battery was fitted in factory, not at the point of sale, so, it can be a few years old. Rate me, plz.

This information comes from the movement manufacture and helps figure out what does what. I also have a yacht timer with no instructions.....hope this helps

A combination of design and technology, ISA 8270 is a precise racing timer developed especially for yachting races, displaying count-down during regatta departures with audible signals, followed by cumulated time during races. The dimensions (25.60mm, H 4.60mm) offer a large variety of opportunities for watch designs. It is suitable for the manufacture of models for gents and ladies watches.

This new calibre is an analogue quartz timer fitted with an alarm function. It displays the hours, minutes, seconds (small jumping seconds at 2 o’clock counter), and date shown by a date window at 6 o’clock. In addition, it allows count-down and race timing. The small hand at 10 o’clock counter and the central hand facilitate the display of count-down and time measurement clearly visible.

Count-down, Racing Timer and Alarm features

ISA 8270 yachting movement not only provides the traditional count-down at 10, 6 and 5 minutes, but also the versatility of setting count-downs at any minute from 10 to 1 minute.

One special feature is that it allows the possibility of recalibrating the count-down at every minute up to the last minute before departure. This latter function allows the navigators to readjust the watch at any time during the count-down to the closest full minute in order to be in line with the official procedure announced by the racing committee (RC) boat so as to get off the best possible start. Audible signals are emitted every minute to alert the progress of count-down. To give higher accuracy, every-second audible signals are emitted during the last 10 seconds count-down to ensure knife-sharp precision. Immediately after the departure, the count-down automatically shifts to the racing timer mode to measure the time of the race event for a maximum of 96 hours. Setting, start/stop and recalibration of count-down and race timing are facilitated by the pushers (at 2 o’clock and 4 o’clock), which are easier to operate.

Thanks to an oversized counter hand and a highly visible flange on the dial that our customers may design, the navigators can best monitor the time remaining before departure and during the entire procedure.

The alarm time is displayed in an analogue mode. Alarm start/stop is enabled by a pusher at 8 o’clock and is displayed by a central alarm hand (12 hours).

Superb performance

Born of precision, accuracy and innovation, ISA 8270 offers excellent quality and performance. Intended for yachting races, this movement gives answer to sports watches requiring indispensable qualities: strength, endurance, agility and outstanding speed.
