Crown Operations
Some water-resistant models (10BAR, 20BAR) have a screw-in crown. When you need to perform a crown operation, rotate it towards you to unscrew it. Then pull the crown out. Avoid applying undue force when pulling.
Rotary Bezel
Rotate the bezel or ring to align its mark with the minute hand. Then you can keep track of how much time has elapsed since you aligned the mark.
Stopwatch
The stopwatch measures elapsed time in 1-second increments up to 29 minutes, 59 seconds.
Important!
– Do not operate the stopwatch with the crown pulled out.
Feedback from users *accumulated information from our own comments and emails, forum threads, socials, reviews, etc.

Enjoy our Edifice EFS-S550 Watch Review
Let’s go back to the bezel. It is massive, pretty, with information indices and a colorful inscription “COUNTDOWN”, which harmoniously combines with other design elements on the dial. The first thing I started to rotate it and, lo and behold, it really rotates with the help of characteristic clicks, and does it only in one direction. This is how the primitive timer function works. Why primitive? Because you do not receive any signal alerts, but simply fix with the bezel the necessary time interval for monitoring. Read Full Review →
Official Marketing Focus from Casio
The EFS-S550 was developed under the guidance of the Scuderia Toro Rosso pit crew. Solar powered operation, highly scratch resistant sapphire crystals, and 100-meter water resistance all combine to make these the ultimate in pit crew chronograph reliability. A countdown bezel also supports crew timekeeping management. It enables countdown of the time to the next scheduled event or the time remaining until a task being performed needs to be completed.
The models in this lineup are available with a choice of yellow, blue, or orange highlight colors, each of which was selected to maximize viewability and sporty looks. There is also a choice of metal, resin, and nylon bands to suit individual preferences for look and fit.
