user guide
, how to tell time  Box: Yes  Light: led
Year: 1978 Price: xxxx
Function: The watch has five functions: hours, minutes, seconds, month and day.

Info: 
This wonderful First Watch was introduced as a learning aid for five to seven-year-olds and teaches how to read any clock. The box included: A colorful, reliable digital watch / A Fun games and how-to book / An exclusive "Hands-on-Time" learning dial.

In 1978 Texas Instruments stated: Digital time is here to stay, but today's youngsters still need to know how to read conventional "big hand-little hand" time.  Today, 30 years later, we know more - most kids wear old-style watches or use the analog clock of their sell phones.

My first watch !!! This was the first watch my parents, Teresa and Giorgio, gave me in the 1970s, one of the reasons my passion for Texas Instruments was born. The factory (Cittaducale, Rieti, Italy) was located near my home and was the beating heart of a true technological revolution.

300x235 calcWhat is the Tritium lighting?

With Tritium is has a constant source of light that does not require any additional source of energy. There are no buttons
to push. Tritium is active every day for up to 25 years. All you have to do is look at the clock and you know exactly
what time it is. Tritium provides easy reading, the light is perfectly visible in complete darkness. No other lighting can
claim those benefits.

To date, after all these years, many watches of the museum that used this technology is no longer visible to the decay
of tritium atoms.

italy SChe cosa è l'illuminazione Tritium?

Con Tritium si ha una costante fonte di luce che non richiede alcuna fonte di energia aggiuntiva. Non ci sono pulsanti
da spingere. Il Trizio rimane attivo giorno dopo giorno per un massimo di 25 anni. Tutto quello che dovete fare è guardare
l'orologio e si sa esattamente che ora è. Tritium fornisce una facile lettura, la luce rimane perfettamente visibile al buio
completo. Nessun altra illuminazione può rivendicare tali benefici.

A oggi, dopo tutti questi anni, molti orologi del museo che utilizzavano questa tecnologia non è più visibile per la
decadenza degli atomi di trizio.
