Manufacturer information and review searches have been checked. No eligible independent overall rating was verified, so this product remains unscored.
How we calculate scores →About this gear
The OSTC 5 is the large-screen model in this comparison, built around a 3.7-inch AMOLED display. Heinrichs Weikamp lists Bühlmann gradient-factor and VPM-B options, full-trimix capability, a digital compass, Bluetooth and wireless charging. An optional S8 connection supports specified external sensor applications.
Consider before buying
The display is a reason to inspect the unit, but it also makes wrist fit and mounting important. Confirm installed firmware, selected algorithms and optional interfaces rather than assuming every pictured connection is supplied. Sensor compatibility needs confirmation for the actual application.
Our take
Consider the OSTC 5 when a larger screen helps you read the information you need. The nano is a more relevant comparison when minimal size is the priority, and the OSTC 2 sits between them by published screen size. No eligible independent overall rating for the exact OSTC 5 was established in this pass; older OSTC 4 reviews are not substitutes.
