Featuring a square face and a vibration alarm, the W-738 is designed for everyday wear and active use.  
A carefully balanced mid-size case, measuring 47.0 mm by 42.8 mm with a profile of 13.4 mm, sits naturally on the wrist for all-day comfort. A shorter hole pitch allows finer adjustment of the band, making vibration alerts easier to feel.  
The display is large and easy to read at a glance. Controls are arranged for simple operation, with the start/vibration setting button clearly identified by its shape and accent color. The center light button is compact but easy to press, even during movement. 
The watch also offers 100-meter water resistance, an approximate 10-year battery life, and a high-brightness LED backlight, making it a reliable and versatile companion for daily life, sports, and work.
