The exact reference matters: the AL-525K3VE6 and AL-520G3VE6 differ in movement and design details, while the wider range also includes bracelet and GMT configurations. Alpina’s current product listings describe several compact steel models, but do not establish an official “retro” design story or a specific new-release date.
What does “retro touch-up” mean here?
“Retro touch-up” is not an official Alpina description established by the available product listings. Those pages identify a current Seastrong Diver Extreme collection and specify its materials, dimensions and functions; they do not confirm a historical design lineage or explain the phrase as a deliberate vintage reference. The reviewed sources also do not establish an exact launch date or a limited production quantity.
The collection’s name can therefore be used to identify the watches, but claims about a vintage revival, historical inspiration or a newly announced release should not be inferred from the listings alone.
Which Seastrong Diver Extreme models are listed?
These are the US prices shown on Alpina’s pages when reviewed, not guaranteed current prices. The UK listing is included separately because prices vary by market.
#1 Best Overall
- The Seastrong Diver Extreme Automatic is housed in a 39 x 40.50mm steele case and features three central hand-polished hands that sit at the heart of a dial textured with Alpina's iconic triangular emblem, punctuated by a date window at 6 o'clock.
- For maximum readability, both the hours and minutes hands and the hour markers have been coated with luminous material and the date window features black figures on a white background.
- WR to 300m, and comes on a bright orange rubber strap.

How do the two named automatic references differ?
AL-525K3VE6: khaki dial and date
Alpina lists this version with an AL-525 automatic movement, date display at 6 o’clock, a khaki sandblasted dial and a black rubber strap. Its case measures 39 × 40.50 mm, and the manufacturer rates it to 300 m water resistance. The US page reviewed listed it at $2,295. [Alpina product page]
AL-520G3VE6: special-edition styling
Alpina describes the AL-520G3VE6 as an “Alpina X The Real Time Show Seastrong Diver Extreme Automatic Special Edition.” Its cited US listing specifies a 39 × 40.50 mm steel case, black rubber strap, matte black ceramic unidirectional diving bezel, AL-520 automatic caliber and 38-hour power reserve. It listed at $2,395. That listing does not establish a production quantity, so “special edition” should not be read as evidence of a particular limit. [Alpina product page]
Rank #2
- The Seastrong Diver Extreme Automatic GMT. One movement and three-time bands.
- The GMT is displayed with a second central hours hand-known as the 'home time zone'-while the central hours, minutes and seconds hands denote the time wherever the wearer is on their travels; the date window at 6 o'clock is naturally synchronized with this time band. No additional controls are required to operate the GMT function: everything is done via the single, secure screw-crown at 3 o'clock.
- Relentless travelers in need of a third-time band can also use the bezel with its 24-hour markings.
- This style features the signature Alpina triangle pattern dial in a silver tone, and comes on a black rubber strap.
What should you check before comparing or buying?
- Match the reference number. Do not apply the AL-525K3VE6’s date, dial or water-resistance specifications to the AL-520G3VE6, or assume that a collection-level GMT or bracelet entry has the same details.
- Compare the configuration. The listed options include rubber straps, a bracelet model and a GMT version; the strap or bracelet changes both the appearance and the page-listed price.
- Treat water resistance as a manufacturer rating. Alpina specifies 300 m for the cited AL-525 references. The evidence here is the maker’s rating, not an independent test result.
- Confirm local price and stock. The amounts above are prices shown on the cited regional pages when reviewed. They may change and should not be treated as universal or permanent.
For a reliable comparison, use Alpina’s individual product pages for exact reference-level specifications and its US collection page to see the range of configurations and listed prices.
