Heart Rate Sensor Replacement Part Does it matter if it's LTE or GPS?

Hi all, I’m new here. Sadly, the back of my heart rate sensor broke (the black glass thing with circles on the back of the watch). My Apple Watch is S3 42mm GPS and LTE. The part I found on ebay is the only one I could find and it’s not LTE, just GPS. Anyone have an idea if I just used the GPS sensor instead, would it work the same? I don’t mind missing out on the whole LTE feature, I just want my sensor to work again.
