According to a new report from Yahoo Finance, Fitbit's smartwatch will not launch until the fall because of certain production issues.
The company's first proper smartwatch will be accompanied by its first pair of Bluetooth headphones.
Fitbit's design team also ran into problems making its smartwatch fully waterproof, even though that's a key design element for the Apple Watch Series 2.
So far, the closest Fitbit has come to building a smartwatch is its Blaze activity tracker.
"In one of the more final prototypes, the Global Positioning System wasn't working because the antennae wasn't in the right place", one of those sources told Yahoo Finance. It remains unclear whether the Fitbit smartwatch will be dubbed as waterproof when it's eventually launched later this year.
Wearables vendor Fitbit has always been recognised as a go-to brand for fitness trackers of all shapes and sizes, but while it dipped its toe into the smartwatch market with last year's Blaze, the company hasn't fully dived in to create its attempt at an Apple Watch killer. It will feature a color display with 1,000 nits of brightness - which will be twice as bright as Apple Watch Series 2, a built-in Global Positioning System chip, heart-rate monitoring, the capability to complete contact-less payments, store and play Pandora songs without a phone, and around four days of battery life.
Fitbit's device is predicted to cost around $300 and will be housed in an aluminum unibody design that allows users to swap out bands of different styles and colors. Some of the production mishaps were technical, with the product design being an issue in some cases. Several employees who saw the design complained about it, the source said. "It was very retro-looking with the lines and stuff - definitely not sexy", they said. "We don't have news to share at this time", she said.
