COROS Pace 4 Pro Leaked: New Sports Watch Spotted in Indonesian Certification Database

COROS appears to be preparing a new addition to its popular Pace series. The upcoming COROS Pace 4 Pro has surfaced in Indonesia’s official telecommunications certification database, giving us the first solid indication that a new Pro-branded running watch could be on the way.

The listing was discovered by WearableFans in Indonesia’s e-Sertifikasi DJID (SDPPI) database. While the certification does not reveal the smartwatch’s specifications, it confirms that COROS has registered a device under the COROS PACE 4 PRO name.

COROS Pace 4 Pro Appears in Official Certification

The COROS Pace 4 Pro was listed in Indonesia’s official telecommunications certification system on August 5, 2026.

According to the certification record, the smartwatch carries the model number W337 and was submitted by PT Denka Pratama Indonesia. The document also identifies China as the country of origin.

Here are the key details currently available:

The appearance of the product under its apparent retail name is particularly interesting because it suggests the device is moving through the regulatory process ahead of a potential commercial launch.

What Could the COROS Pace 4 Pro Offer?

At this stage, COROS has not officially revealed the Pace 4 Pro’s specifications or features. The Indonesian certification primarily confirms the device’s existence and regulatory approval process rather than providing detailed hardware information.

However, the “Pro” branding naturally raises expectations for upgrades over the standard Pace lineup.

COROS Pace watches are known for focusing on runners and athletes, with lightweight designs, GPS tracking, training features and long battery life. A Pace 4 Pro could potentially expand that formula with more advanced hardware while retaining the series' performance-focused approach.

Possible Upgrades Could Include

Improved GPS Accuracy:
A new-generation GNSS system, potentially including dual-frequency positioning, could improve tracking accuracy in challenging environments such as dense cities, forests and mountainous areas.

Offline Mapping:
More advanced navigation and offline maps would make the watch more useful for trail runners, hikers and athletes who train away from their phones.

Premium Materials:
COROS could introduce upgraded materials such as sapphire glass or a titanium bezel on the Pro model, although there is currently no official confirmation of these features.

Enhanced Health Sensors:
An updated optical heart-rate sensor or other sensor improvements could provide more accurate training and recovery data.

It is important to note that these features remain speculation until COROS officially announces the watch.

Why the Pace 4 Pro Could Be Important for COROS

The Pace series has established itself as one of COROS' key product lines for runners and endurance athletes. A Pro model could give the company an opportunity to bridge the gap between its mainstream running watches and its more premium outdoor-focused devices.

If COROS adds advanced navigation, improved sensors and premium construction without significantly increasing the weight, the Pace 4 Pro could become an interesting option for serious runners and multisport athletes.

COROS Pace 4 Pro Launch Date: What We Know

COROS has not announced an official launch date for the Pace 4 Pro.

The appearance of the watch in Indonesia’s SDPPI certification database is an important development, but certification alone does not guarantee that a product will launch immediately or in every market.

For now, the COROS Pace 4 Pro, model W337, remains an upcoming device with limited confirmed information. More details about its design, specifications, pricing and availability are expected to emerge if COROS moves toward an official announcement.

COROS Pace 4 Pro: What Happens Next?

The certification listing gives us the clearest indication yet that COROS is working on a new Pace-branded sports watch.

With the device now appearing under the Pace 4 Pro name, the next major pieces of information to watch for are its official specifications, design, battery life, GPS capabilities, health sensors, pricing and global availability.

Until COROS makes the product official, any leaked specifications should be treated with caution.

For now, one thing is clear: the COROS Pace 4 Pro is real enough to have entered the regulatory pipeline — and runners may soon have a new Pro-level Pace watch to consider.
