Wrist computers with stopwatch in dive mode!

[BluEye Diver]

Apparently this function is rare--which boggles my mind because any Divemaster or Instructor would have good use for it: A timer/stopwatch function WHILE YOU ARE IN DIVE MODE!

As I know, Suunto makes this possible in some of their models, but I am not keen on devices that won't allow me to service the battery myself.

Are there other wrist-style computers that make it possible to run a timer or countdown on the fly when you're already in dive mode?

Tips and leads appreciated

The Kaon, Xeo and Lynx will allow you to use the stopwatch only while diving in gauge mode, not deco mode. The Xen is only a bottom timer and the stopwatch is always available. The Liquivision X1 will allow you to use the stopwatch while diving in any mode including deco mode.

I'm not clear on why you need this. It has never occurred to me n a dive that this would be a useful tool.

A few PADI OW exercises require time eg. freeflow reg, no mask breathing. AOW navigation requires a minute kick cycle. Most computers do not have a second counter. I wear a G-shock on my left and computer on right wrist. Sometimes even just padding a safety stop, I will use the stopwatch.

Which Suunto won't allow you to change the battery?

The Heinrichs Weikamp OSTC 2N has a stopwatch feature. It does not have a user replaceable battery, but it is rechargeable. A brilliant computer. Some of their newer models like the OSTC 3 may also have it, I am not sure.

Works well with Ratio Deco and having a computer running the background.

Because counting sucks.

How precise do you really think those need to be? I just glance at my watch, with no need to push any additional buttons.

I did Ratio Deco for years with just a bottom timer that worked in whole minutes. I have also done the same working with V-Planner. Decompression profiles are not so precise tht you need to have things down to the second.

What would you be counting?

No they aren't but it's a nice feature to be able to hit zero.

IIRC V-planner can also run in 30 second increments
