Solo Watch Band Warranty
Does the solo match band have a Warranty. The one I got with my Watch 7 has developed a tear. Will Apple replace it?
Apple Watch Series 7
all products have warranties, it's not up to the manufacturer but it's set by the laws of your country
Legal - Hardware Warranties - Apple
though mind you warranties only cover production defects discovered after purchase it does not cover user caused damage to the product or loss or theft
