Watch flagship 80s

This is a vintage Casio watch of the 80 available at a ridiculous price on Amazon. I had this watch when I was a kid and nostalgia I recently acquired. 25 years later, I must admit that it has not aged.
Its main advantage is simplicity: no superfluous function, it is sufficient for its basic stopwatch and time for self, even at night thanks to its backlit.
It is extra light (22g) and compact (37,10mm x 33,60mm x 8,70mm). Its light weight makes it a great companion for athletes.

The functions:

Stopwatch: With an accuracy of 1/100 sec, this watch is very useful for timing tasks and sports achievements. Warning, this clock is limited to 1 hour maximum. Indeed, once reached The display of 59:59:99 (59 minutes 59 seconds 99 hundredths of a second), it sets out again to zero (0:00:00). No function countdown nest available on this model.

Alarm: Are offered two types-warning sound. 1 daily alarm on scheduled time (eg 5:45 = daily at 5:45 am) and 1 beep every hour (14.00, 15.00, 16.00, etc.): convenient for those who do not see the time and who want be alerted at the beginning of each hour. Small personal anecdote: college jutilisais this chime ploy to be informed of the end of the hour courses before anyone else (relative to the clock of the school, javançais my Casio watch from a few seconds and threw the first out with class at that).

Lighting: The display of Casio W-58-1VQES can séclairer via the light button. The green LED located on the left side of the screen is not strong enough, so that lighting is not uniform. The right side is dimly lit and therefore fairly readable in the dark.

Format: You can choose between 12h and 24h fashion.
Calendar: The date is configured with the parameters "Weekday" (MO, TU, WE, TH, FR, SA, SU), "Day of the month" (01 to 31) and "number of months" (01 to 12). No management is only possible years, leap days are not taken into account, one must manually set the day each February 29 every 4 years. Otherwise, the date will automatically March 1.

Finish: The case and bracelet are made of sturdy resin. Unfortunately, and experience with this type of watch, the bracelet quune lasts two years before breaking. Its width narrow the subject people to see small handles to children.

Autonomy: The autonomy of the CR2016 battery is announced for about 7 years (depending on use).

Waterproof: You can take a bath or a shower with (OK tightness up to 5 bar or 50 meters). Attention nest she absolutely not designed for diving in the pool or at the beach. Remember to remove before swimming.

Accuracy: +/- 30 seconds per month, which is pretty sketchy.

On most sites, this watch is displayed and costs 30. I recommend you buy it on Amazon where it is available for half the price (about 15).
