Casio Collection Watch W-738H-1AVEF

Presenting the Casio W-738H-1AVEF, a digital watch that revives the aesthetic of 1980s classics with surprisingly modern functionality. At first glance, what defines this model is the combination of its matte black rectangular resin case and the brushed silver-tone intermediate bezel, which frames the LCD display with an elegant and understated contrast. The main screen, with its characteristic greenish-grey LCD background, shows the time in large, legible digits at the centre, with a secondary upper line displaying the day of the week and a secondary time zone. In the upper right corner of the display, icons for vibration (VIB), alarm (bell) and signal indicator are visible. The lower portion of the display includes mode indicators TR, ST, AL and DT, confirming the presence of a stopwatch, alarm and date functions. The bottom button of the case features the word LIGHT embossed on a grey pad, while the top of the bezel clearly reads VIBRATION ALARM. The black resin strap features a horizontal ribbed texture that provides grip and wrist comfort.

Inside works the Casio module 3588, a digital calibre that packs multiple functions into a compact format. The watch offers full time and calendar display with simultaneous hour and day-of-week readout, a second time zone, audible alarm, silent vibration alarm, a split-function stopwatch and countdown timer. The CR2032 battery delivers up to 10 years of autonomy without replacement, and the Illuminator system allows the time to be read in complete darkness. Its 100-metre water resistance makes it suitable for swimming and everyday water activities.

The Casio W-738H-1AVEF belongs to the Timeless Collection, Casio's line of classic digital watches that encapsulates decades of accessible precision engineering. Since Casio launched its first digital watches in the mid-1970s, these models have been inseparable companions for students, travellers and professionals worldwide. The vibration alarm function was introduced to respond to environments where sound is not appropriate, making the W-738H just as suitable in a business meeting as in a library or cinema.
