Why it is interesting

Howlite provides an expressive backdrop for the Freak S. The version’s main appeal is the contrast between quiet stone and constantly working mechanics.

Things to consider

A 45 mm case and 30 m water resistance require a deliberate choice. This is a North American edition; confirm price, availability and purchase terms with an authorised seller.

The model in detail

Meet the watch

White howlite acts as a pale backdrop to the Freak S Howlite’s mechanical sculpture. Its grey veins introduce irregularity where everything else follows geared transmissions. The pairing works: natural material reveals the construction’s depth without competing for brilliance.

Moving elements themselves show the time. The minute pointer is linked to a flying carousel completing a rotation every hour, with an hour disc rotating beneath it. Conventional-hand users will need some adjustment, but looking at the watch becomes a distinct activity rather than a quick phone check.

The UN-251 calibre uses two inclined silicon oscillators and a vertical differential. It averages their rates: an impressive pair of balances does not automatically guarantee better accuracy than every other watch. The Grinder automatic system replenishes a stated 72-hour energy reserve.

Details and limitations

The titanium case measures 45 mm. A white rubber strap echoes the stone and creates a sporting appearance, although water resistance is only 30 m. Separate the visual impression from intended use: this is a complicated collector’s watch rather than a diver.

The North American edition comprises 15 pieces, with a US price of $190,700 excluding tax. The authorised retailer invites customers to arrange an in-store appointment. The price reflects unusual architecture, production complexity and material, but a purchase still begins with a simple question: do you want this particular mechanism on your wrist?
