The Garmin Swim sports watch makes swimming easier. Tell it what length the pool is & let it count your strokes, record your pace, distance, & stroke type, & give you a swimming efficiency (SWOLF) reading. It also has features for timed sets & drills, all of which can then be stored & analysed online. The smooth design means you won't feel dragged down in the water & the watch is automatic: press start before you begin swimming & use the pause button when you stop to rest. The watch is waterproof up to 50m & has a 12 month battery life based on normal usage.
