Ocean Crawler Decompression Timer - Yellow

Every single Ocean Crawler has been immersed in water and has been thoroughly tested to withstand pressures up to 2000 feet. This makes it a must-have underwater accessory for water sports enthusiasts who scuba dive, spearfish, and even do ocean-bed exploration.

This special limited edition features a decompression timer dial that indicates the required decompression stops during a dive. The watch also features an all-Sapphire unidirectional rotating bezel which bears hour-markers filled with seven layers of Swiss C3 Lume. Powerful C3 Lume on the key elements guarantees perfect readability when deep diving.

The movement inside is a regulated Sellita SW200-1 movement. It has a beat rate of 28,800 vibrations per hour and has been enhanced for added accuracy.

There are only 100 units per color made of the Ocean Crawler Decompression Timer and all are stamped with a unique serial number out of a total of 100.

How to use the Ocean Crawler's Decompression Timer? 

Check your depth by using four concentric indicator rings, each corresponding to a specific dive depth. To select your dive depth, refer to the scale at 12 o'clock. The depths are displayed in meters on the left (25/30/35/40) and in equivalent feet on the right (85/100/115/135). For example, if you plan to dive to 25 meters / 85 feet, use the corresponding ring, and if diving to 30 meters / 100 feet, use that ring, and so on, up to a maximum of 40 meters or 135 feet.

Once you have determined your dive depth, the next step is to read the decompression times indicated in a circle around your chosen depth ring. Decompression time is relative to your total dive time; the longer the dive, the more decompression is required. The indicator will inform you of the required decompression stop duration based on how long you've been underwater. For instance, for a 25m-29m dive (first inner ring), decompression stops are indicated after 34 minutes. Therefore, for a dive duration of 35-40 minutes, a five-minute stop is required; for a dive duration of 41-50 minutes, a 20-minute stop is needed, and so on.

To use the timer, set the minute hand to 12 when you begin your dive, and use it to time your underwater exploration. When it's time for your decompression stop, you can measure its duration using the rotating bezel. Align the numeral on the bezel corresponding to your required decompression time (e.g., numeral 20 for a 20-minute stop) with the minute hand. As the minute hand reaches zero (indicated by the luminescent 12 o'clock marker on the bezel), it's safe for you to return to the surface.
