This is the kind of timer for those who are in science, cooking, or intensive time exercises like yoga. It can even work for laps in the pool. The time itself is splash-proof and features an extra large display with an hrs/mins or mins/secs setting. So it can go from 1 second to up to 20 hours. Also featuring a magnetic clip, the product is something I wish I had found earlier after getting several timers wet in the kitchen. Though its fairly expensive (approx. $20), it will last you years. Well worth it.
