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).
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.
When the trend of sportive and fashionable quartz watches prevails, this new Swiss Made ISA 8270 priced competitively with outstanding performance answers the expectations of an increasing market demand and customers, who wish to add a number of value-added exceptional designs to their next collections with strong sporting character.
