Garmin is certainly one of the leaders in fitness wearables and sports watches, but one of the missing features that users hoped would come with the Vivoactive 3 is music storage and it looks like their prayers have been answered in the form of the Garmin Forerunner 645 music. I recently wrote about the leak of the Garmin Forerunner 645 when the first images appeared, but now it appears the new running watch from Garmin will be coming sooner than expected.

Garmin Forerunner release

Following the leak of the Garmin Forerunner 645 last month, Garmin this time have accidentally leaked an image along with spec’s, features and pricing on their own website.

Garmin Forerunner 645 design

The Garmin Forerunner 645 is going to sport the same design as the Vivoactive 3, The Forerunner running watch will also weigh in at 42g with a stainless steel bezel and 20mm quick release silicone watch bands. It sounds like the Forerunner 645 will not feature a touchscreen, but instead feature physical buttons to navigate the watch. It will also be waterproof to 5ATM, but interesting it does not have an open water swimming profile

In terms of the screen specs, it seems we can expect a 1.2-inch, 240 x 240 display, There’ll also be a heart rate monitor on board with built-in GPS/GLONASS to track your activities.

Garmin Forerunner 645 features

Garmin did a very good job of leaking the features of the Garmin Forerunner 645 and below I will give you a break down of the key features and observations

Garmin music storage

Based on the specs the Forerunner 645 will come in two versions; one with music support and without.

The 645 Music will let you store 800 songs and will let you pair Bluetooth headphones like you can on the Fitbit Ionic. The Forerunner 645 music also appears to have the ability to stream music and store music for offline playback from a streaming service, but according to the leak it will not include Spotify and this may be due to the fact Samsung has an exclusive deal with Spotify at present

Garmin Forerunner 645 music versions

Forerunner 645 sports tracking

The Garmin Forerunner 645 will track a variety of sports, but its main aim will be run tracking. It will feature Advanced running dynamics with compatible HR strap or Running Dynamics Pod and features a wrist-based heart rate monitor, which I suspect will be the same featured in the Fenix 5 and Vivoactive 3.

Forerunner 645 music will also be waterproof to 5ATM like other Garmin fitness wearables and will support pool swimming One thing I did spot is that it didn’t feature an Open water swimming profile on the specs sheet and this would be a miss for triathletes wanting to use the Forerunner 645. Speaking of try mode, it does not feature a multi-sport mode, so its a no for triathletes. The Forerunner 645 will not support Garmin’s HR-Tri chest strap for downloading of HR data post a swimming workout.

Looking at the specs sheet it will also feature Garmin’s new cardio and strength tracking along with other activities like Elliptical Training, Stair Stepping, Floor Climbing, Indoor Rowing and Yoga. Along with the sports tracking the Forerunner 645 will also feature step tracking, floors climbed, activity minutes and all the usual Garmin all day tracking stats.

One of other missing features I spotted was power meter support for cycling on the Forerunner 645. According to the specs sheet, the 645 music didn’t support the Garmin Vector power meter nor third-party power meters.

Garmin Pay on the Forerunner 645

Garmin will also include the wrist-based contactless payments service Garmin Pay on the Forerunner 645. However, as it currently stands Garmin Pay has got off to a slow start with the Vivoactive 3 with a very limited launch. So let’s see how much traction Garmin make with the payment service, but adding to additional wearables is a step in the right direction.Forerunner 645 with Garmin Pay

Garmin Forerunner 645 music smart features

The Forerunner 645 music will also include smart features like current Garmin devices, including Connect IQ support, the ability to respond to notifications and control music playback. I am not personally a fan of smart features on a fitness watch, but that is just down to personal preference.

Garmin Forerunner 645 release date

Due to the fact that Garmin leaked this time via its own website, I suspect the Garmin Forerunner 645 to be released in December 2017 or at the latest January 2018. I have reached out to Garmin for a comment and I was told by the PR people that they don’t comment on unreleased products, I did expect that if I am honest.

Garmin Forerunner 645 price

The Forerunner 645 will be priced at $449/£399 when released and again this was pulled out of the Garmin product page on the Forerunner 645 before it was pulled. However, I do think that this price is for the non-music 645 and the price could be higher for the 645 music version.

Garmin Forerunner 645 opinion

Based on the leaked specs and the renders of the Garmin Forerunner 645 I think this will answer a lot of the users of Garmin’s fitness wearables requests for music storage and I am hoping that the streaming services are a good range. My biggest observation is that the Forerunner 645 based on face value is similar o the Garmin Vivoacive 3, but with music storage and advanced running features and the biggest question will be, is the extra $150/£100 worth paying to get music storage and advanced running features. My personal view is that if you are a serious runner then it won’t be a choice between the Vivoactive vs the 645, but the Forerunner 935 and the forerunner 645 given the small difference in price.

Let me know what you think in the comments below.

The 645 has been speculated about for sometime! I wished it would just come. I am not 100% sure music is going to work well through
