They share identical specs in every respect, except for product name and color options. There isn’t even a battery life upgrade, which seems unthinkable but is no less true.
Nevertheless, they are both very good golf watches that will keep most golfers happy with a solid selection of golf features and a few extra sports features like running, cycling and basic activity tracking.
Key Similarities - Garmin S40 vs S42
Key Differences - Garmin S40 vs S42
You’re probably thinking, surely there are some actual differences between these golf watches. While your instincts may be correct, it’s fundamentally clear that the Garmin Approach S42 is actually the Garmin Approach S40, albeit with a slightly different product name.
The S42 is not an upgrade. It is literally the same watch, with exactly the same specs, and a slighty different selection of colors to choose from.
Personally, I find this quite disappointing, because it is misleading. I’m not sure which genius at Garmin made this decision, but I can say that he/she put commercial interests (new models sell better) ahead of the interests of their customers. That is how you end up with a disingenuous upgrade like this.
