The Alpina Alpiner Extreme Automatic California Dial, reference AL-525GRG3AE6, pairs a green dial with a compact, cushion-shaped stainless-steel case and black rubber strap. Its defining detail is the California-style layout: Roman and Arabic numerals share the dial with dashes and triangles. Alpina lists a 200 m water-resistance rating and an automatic AL-525 movement.
What is the Alpina Alpiner Extreme Automatic California Dial?
It is a specific green-dial version of Alpina’s Alpiner Extreme Automatic, identified on the brand’s Canadian product page as reference AL-525GRG3AE6. The listing specifies a stainless-steel case, black rubber strap, sapphire crystal with anti-reflective coating, and luminous hands and markers. Alpina’s Canadian product page lists the watch at CA$2,795; that is a regional listing, not a universal or guaranteed current price.
What does “California dial” mean here?
Alpina uses “California dial” for the combination of Roman numerals, Arabic numerals, dashes, and triangles on this model. The mixed markers give the face its distinctive look; Alpina says the arrangement is intended to make time easier to read from different angles. That is the manufacturer’s design rationale, not a result from independent legibility testing.
Case dimensions and materials
The case is stainless steel, with a cushion-style outline. Alpina’s technical table gives a case length of 40.4 mm, a thickness of 11.5 mm, and a 19 mm lug width. In its descriptive copy, the brand instead calls the case 39 x 40.5 mm. These are two descriptions from the same listing, so the figures should not be collapsed into a single measurement. The 19 mm lug width is the relevant listed dimension when considering strap compatibility.
#1 Best Overall
- The Alpiner Extreme Automatic is a 41 x 42.5mm rugged sport watch.
- At the heart of the design, a strong brushed-finish cushion case featuring a black dial with a date window at 3 o'clock and a see-through case-back.
- The integrated black rubber strap (with no joining link with the case), made of textured rubber offers as much comfort as strength and modernity.
- The rubber grip allows for ease of handling with bare hands or with gloves.
- WR to 200M.
Movement, functions and power reserve
The exact-reference Canadian listing specifies an automatic AL-525 movement and hours, minutes, seconds, and date functions. Alpina’s movement description says the mechanism is wound by motion of the wearer’s arm. The retrieved page for this reference does not state its power reserve.
For family context only, Alpina’s page for the sibling California-dial reference AL-525BRG3AE6 lists a 38-hour power reserve and describes the AL-525 as based on the SW200. Those details are not confirmed in the retrieved technical information for AL-525GRG3AE6 and should not be treated as independently verified exact-reference specifications. Alpina’s sibling-reference page covers that other variant.
Rank #2
- Built for total freedom, the Alpiner Extreme Solarmetre is the first solar-powered watch from Alpina
- Hours, Minutes, Seconds, Date
- Silver-Tone Stainless Steel 37.5mm Case
- Anti-Reflective Sapphire Crystal
- 100M Water Resistant and Limited Warranty
Water resistance and intended use
Alpina rates the AL-525GRG3AE6 at WR200, or 20 bar/660 ft, and associates the rating with swimming and marine sports. This is the manufacturer’s stated rating and suggested use; it does not establish suitability for every water activity or condition. Alpina’s general service guidance also advises avoiding extreme temperature changes, such as putting a watch into very cold water after prolonged sun exposure. That is general brand advice, not a model-specific service interval. Alpina’s service document provides the care guidance.
