Linde Werdelin Biformeter watch making it pretty slim in reality

Everything is displayed on the Land Instrument's surprisingly sharp gray four-tone 128x128 pixel LCD screen. There is a backlight that can be activated during low light situations for a few seconds at a time. Linde Werdelin's other Instrument, the Sea Instrument, features a color screen. I don't really think that a color screen is necessary on a device such as this. To properly display different colors the backlight would need to be on too much and significantly reduce the battery life. A gray scale screen is just fine here, and accordingly, it has a good level of battery life with about 60 hours of standby time. This will give you a good day or two of usability, but it will need to be recharged. It is important to note that Land Instrument is not a watch per se, meaning that it is not made to be worn all the time like a watch. If you do, you'll need to charge it pretty regularly (makes me think of the Microsoft SPOT watches). Right out of the box, the Land Instrument cannot be worn on your wrist by itself. However, a special wrist strap can be purchased separately from Linde Werdelin that you'd probably want to get if you don't have a Biformeter watch. The Land Instrument also comes with a world charger. If you take your Land Instrument on adventures, it'll be a good idea to bring along a solar charger or other types of charging equipment. The Land Instrument is a nice feeling device, and is built to be light (41 grams) yet durable. The body is constructed from aircraft grade aluminum, with a mineral glass screen. While the device looks thick, most of the underside in concave allowing for it to fit on a Linde Werdelin Biformeter watch - making it pretty slim in reality. Size wise, it is about 44mm long, 52 mm wide, and 18mm tall at its highest point. Two little hinged clips on the side of the case allow for it to be clipped on to a Biformeter watch, charger, or the Land Instrument's accessories that come with it or can be purchased from Linde Werdelin.
