Right now, you can pick up the Polar Grit X multisports GPS watch, together with the Polar H10 heart rate monitor, a bike mount and a saddle bag for £314.30 at Wiggle. That's a saving of 30% off the regular asking price, and it's a genuinely great deal.
The Polar Grit X has never dropped below £314.44 at Amazon – and that's for the watch alone, not this entire bundle. The H10 heart rate monitor usually sells for around £60 by itself, and the extra handlebar mount and saddle bag sweeten the deal even further.

Polar Grit X bundle:
£449 £314.30 at Wiggle
Save £134.70 This deal from Wiggle absolutely smashes the best deals at Amazon, where you'd usually expect to pay at least £400 for everything you're getting here. We're not sure how long stock will last, but we wouldn't be surprised if it sells out soon.
The Polar Grit X is a seriously tough watch, and when we tested it we were particularly impressed by its advanced training tools (including suggested sessions based on your fitness and previous workouts), plus its in-depth recovery insights that help make sure you're getting enough rest between sessions.
Data from both the Grit X and the H-10 heart rate monitor syncs automatically with Polar Flow, which is one of the best fitness apps around. All your stats are clearly presented, including activity totals, progress reports, sleep patterns, and training plans. Overall, it's a great little package, and one that gives Garmin's top-end watches a real run for their money.
