At first glance, one may mistake Hublot’s Big Bang Alarm repeater as a chronograph watch because of the two pushers and the two sub-dials.

This isn’t a chronograph watch but the brand’s new Alarm Repeater launched at the 2015 annual BaselWorld watch fair. This watch is not to be mistaken for the traditional minute repeater which chimes the time on demand.

Why is it called the “Alarm Repeater”? This, as the brand points out, is because “the alarm clock is a complication which belongs to the chiming clock category”.

While this alarm repeater function does not chime on demand (upon manual activation) of the current time, it instead chimes the programmed alarm time.

This programmed alarm time is set via the crown and it is indicated by the counter located between the four and five o’clock positions. This 24-hour counter has the hour and minute hand for easier reference of the set alarm time.

 

 

What’s more, the chiming mechanism uses the hammer that strikes the gong to sound the alarm. However, in this case, it is a repetitive alarm sound and not the actual time as provided in a minute repeater.

Hublot’s Alarm Repeater features the second time zone display as well. The time of the hour is displayed on the 24-hour counter located at 11 o’clock and this is normally set to home time (the time zone where one originated from).

Local time is shown on the larger off-centred dial and this is the time zone where one is currently at.
