Water-resistant
You’re covered to 50m, so dance in the rain if that’s how you want to work out today.
Sense 2 is designed to comply with a water protection rating of 5 ATM under ISO standard 22810:2010 when manufactured, but it is not waterproof. Water resistance is not a permanent condition and decreases or is lost over time due to normal wear and tear, repair, disassembly or damage. Dropping your Sense 2 may result in loss of water resistance. Sense 2 is designed to be used in shallow water and should not be used for activities involving water at high velocity or high temperature. Some Sense 2 bands are not water resistant.

The Suggested Equal Monthly Payment shown with your Google Store Financing account may be greater than the required minimum monthly payment that will be on your billing statement when you use the 12 month promotional financing offer.
This payment equals the promotional purchase amount (which is shown as Example purchase price above) divided by 12 (excluding taxes and shipping charges). This would pay off the promotional purchase amount within the applicable promotional period, but only if there are no other balances on your account at any time during the promotional period and you make your payments on time. Your total payments will equal the amount of the promotional purchase amount.
If the promotional purchase amount is not paid in full within the applicable promotional period, interest will be charged to your account from the purchase date and your total payments will be greater than the amount of the promotional purchase amount.
- The amount of a single transaction regular purchase is determined before taxes and shipping are added to the purchase and before any discounts are applied.
No interest will be assessed on the promotional purchase balance (including shipping and taxes) if you pay the promotional purchase balance in full within the applicable 12 month promotional period.
If you do not, interest will be assessed on the promotional purchase balance from the date of the purchase.
Depending on the purchase amount and payment allocation, the required minimum monthly payments may or may not pay off the purchase by the end of the promotional period. Standard account terms apply to non promotional purchases and, after this promotion ends, to your promotional purchase. For new accounts: Phone purchases (any transaction that includes a phone) APR is 0.00%. All other (regular) purchases, APR is 29.99%. Minimum interest charge is $2. Existing account holders should see their credit card account agreement for their applicable terms. Subject to credit approval. See “Deferred Interest Promotions with Minimum Monthly Payments” in section 2 of the Google Store Financing Credit Card account Agreement.
