While doing my daily routine of scanning international certification databases for unannounced wearable tech, I spotted a fresh filing in Indonesia’s official e-Sertifikasi DJID (SDPPI) database.
It looks like COROS is preparing to expand its popular lightweight performance lineup with a new model: the COROS Pace 4 Pro.
The Certification Details
The listing was officially published on August 5, 2026, registered under COROS’s local Indonesian distributor, PT Denka Pratama Indonesia. Here are the exact specifics extracted directly from the registry filing:
-
Marketing Name: COROS PACE 4 PRO
-
Model Number: W337
-
Brand: COROS
-
Certificate Number: 125116/DJID/2026
-
Issue Date: August 5, 2026
-
Applicant: PT DENKA PRATAMA INDONESIA
-
Country of Origin: China
What This Model Tells Us
Regulatory approvals like the Indonesian SDPPI are often one of the final steps before a manufacturer launches a device commercially in global markets. When a watch appears in these databases under its actual marketing name rather than just an obscure internal code, an official product announcement is usually only a few weeks to a couple of months away.
The model code W337 designates a completely new hardware platform for COROS. The “Pro” naming convention suggests this watch will bridge the gap between their ultra-lightweight entry running watch and their higher-end outdoor gear (like the Apex and Vertix series).
While the listing does not reveal full internal hardware specifications, a “Pace 4 Pro” designation hints at key upgrades users have been asking for:
-
Enhanced Mapping: Potential offline topo map support packed into a lightweight casing.
-
Display Upgrades: A potential shift toward a high-contrast AMOLED panel or a higher-resolution Memory-in-Pixel (MIP) display with upgraded glass protection.
-
Build Quality: Possible inclusion of premium materials like a titanium bezel while maintaining the signature lightweight feel of the Pace series.
I will continue monitoring other regional databases like the FCC, SIRIM, and RRA over the coming days for additional antenna tests and hardware details.
