Swimmers - is there a cheap watch/stopwatch that is really waterproof?

[Sadik]

I want to time myself in the pool, and then have a watch to know the time when sea swimming - and wondering if there's anything relatively cheap that would fit the bill. Been looking on Google, but it's all things that count laps etc (though would that mean I didn't have to count my lengths???)

...?

I used to have a watch that counts laps. It was pretty good, has run out of battery. It was about £50 from Amazon. I just looked and they seem more expensive now. swimovate was the make.

Until I took up running, I used Decathlon sports watches. I had a model that had watch, timer and chest strap for heart rate.

The Decathlon ones look just the ticket, thanks MrsMook!
