Polar M430 Original Strap
The original Polar strap for the M430 is the replacement designed by the manufacturer for its GPS running watch. It is not a generic strap or an import: it is the piece Polar has developed specifically for the M430 Custom attachment. That specificity is what guarantees that the strap fits the case without play and that the watch stays stable on the wrist during training.
The strap is made of silicone, a material that does not absorb sweat and is cleaned with water. It is supplied in two sections and includes spring bars for the change. The closure is a classic pin buckle, with multiple holes that allow the strap to be adjusted to the wrist without being loose. It is a strap designed for running and training.
The original is designed for direct mounting, without adapters or play, and for the watch to remain the same training instrument it was when it left the factory. Those looking for a strap that does not alter the fit, does not introduce movement into the case and maintains the sensor's reading will find in the original the option Polar designed for that specific watch.

Why choose this strap?
Custom attachment designed by Polar for the M430
The M430 strap is not a standard 20 or 22 mm one: Polar designed it with a specific attachment for this case. That guarantees it fits without play and that the watch does not move during training, something a generic strap does not always achieve.
Silicone that does not absorb sweat
Silicone is cleaned with water, does not retain sweat and does not degrade with sports use. It is the material Polar chooses for its training straps, and the one that keeps the strap in condition after many sessions.
Spring bars included
The replacement includes the spring bars, so the change can be made at home without the need for a watchmaker. It is a practical detail for those who want to replace the strap without travelling.
