The shock-resistant Suunto Observer is a tool built for outdoor challenges, but its timeless design makes it wearable in any situation. The Observer is 1/3 smaller in both diameter and width than the first generation Suunto Watches (Vector, Altimax, etc). It also features a chronograph, which previously was only offered in the Navitech but is now discontinued. Available in 5 different material combinations: stainless steel housing with elastomer strap, stainless steel housing with stainless steel strap, and titanium housing with titanium strap. Water Resistant to 100m / 330 ft. (3 times deeper than the other non-dive watches). Metal Strap versions consist of metal links over an Elastomer strap with a hinge type opening. Our biggest complaint about the Observer is the Alarm Volume; in order to get all of the electronics in the small casing, something had to give, and it was certainly the alarm speaker size. If you normally use a watch alarm, this one is at best about 1/2 the volume.
