Its 37.5 mm stainless-steel case, slim 8.35 mm profile and 100 m water-resistance rating make it a compact sports-watch option; official listings show rubber-strap and bracelet versions with different dials and regional prices. Whether it is worth buying depends on whether you want the low-maintenance solar concept and its specific design, rather than a watch with independently verified performance data.
What is the Alpina Alpiner Extreme Solarmetre?
It is a solar-powered member of Alpina’s Alpiner Extreme line. Alpina’s US product pages identify the movement as caliber AL-140 and describe it as powered by any light source, eliminating the need to replace watch batteries. Alpina’s UK listing calls the movement Q100 Solar and identifies La Joux-Perret as its maker. These are manufacturer descriptions; the available product information does not establish independent movement testing.
Alpina claims a 10-month power reserve without exposure to light. The figure is a manufacturer specification, not an independently verified test result. Alpina describes the watch as continuously powered by light, but the product pages do not provide independent data on charging speed or real-world accuracy.
What are the specifications?
For the blue rubber-strap reference AL-140N3AE6, Alpina lists the following specifications on its US product page:

What should you know about fit and water use?

Alpina’s Canadian page gives a weight of 96.7 g and a 24.8 mm lug width for the burgundy bracelet reference. The blue rubber model’s listed lug width is 15.25 mm. These figures are tied to different configurations, so do not assume a single universal lug measurement or that replacement bands are interchangeable. Confirm the exact reference and attachment before ordering a strap.

There is not enough evidence in the official listings to judge accuracy, charging speed, long-term durability, comfort or service cost against alternatives. Treat the reserve and light-powered operation as Alpina specifications, not independent test findings. If those performance details are central to your decision, seek credible testing or service information before buying.
