New: Speake Marin Openworked Sandblasted in titanium and red gold

The prices for the Speake Marin Openworked Sandblasted Titanium are as follows:

  • CHF 22,200 (Sandblasted Titanium 38mm)
  • CHF 22,600 (Sandblasted Titanium 42mm)
  • CHF 34,000 (Sandblasted Red Gold 38mm)
  • CHF 38,700 (Sandblasted Red Gold 42mm)


The novelties are part of the Openworked collection, a family of 13 watches characterised by the open worked dial on the Piccadilly case. The case was the first to be designed by Peter Speake-Marin during the formative years of the independent watchmaker. Peter has since left the maison and also The Naked Watchmaker which he co-founded in 2017. And case design was revised by celebrated designer Eric Giroud in 2017. This new release introduces the Speake Marin concept of the sandblasted grey dial, which is identical for both new models.

Two case sizes are offered in each of the two case metals. One in 38mm and the other in 42mm. All specifications are exactly the same except for the case size. The larger 42mm features a wider bezel. Visually, we prefer the smaller 38mm case for the elegant ease it pulls off.

The movement remains the same SMA01, designed and made by Le Cercle des Horlogers. This is a well tested movement which appears in many of Speake Marin’s watches, and carries COSC certification.

Pricing seems a bit on the high side in our view, CHF 22k is a rather handsome sum for a titanium watch, albeit with an open worked dial.

Release information


In 2023, Speake Marin raises the question of harmony and balance.

Revealing strong watch architecture, The One & Two collection anchor the Speake Marin contemporary style. The Piccadilly case reflects the iconic case of this collection.

More than a luxury collection, the One&Two embodies elegance in creativity.

The One & Two Openworked Collection continues its journey with the Sandblasted Titanium and the Sandblasted Red Gold.


In an ideal world where choices define our journey, Speake Marin invites you to explore its One & Two Openworked collection, a testament to craftsmanship and tradition. You will be transported along a path inspired by the great watchmakers, masters of time, for a unique escapade in La Chaux de Fonds, where the expression of art and craftsmanship blends with boundless human creative ambition.

Each powerful and sublime interpretation by master watchmakers involves sharing and passing on our tradition and savoir-faire. This is why Speake Marin has chosen to highlight an outstanding decoration as a tribute to this artisanal know-how through the new Openworked Sandblasted.


Speake Marin has imagined two new variations of the One & Two Openworked. While bearing a strong family resemblance, they embody two distinct personalities: the Openworked Sandblasted Titanium and Sandblasted Red Gold.

The sandblasted grey dial, identical for both new models, endows each of them with a unique appearance thanks to the different light reflections on the red gold and titanium cases.

The new Openworked Sandblasted timepieces are a clear expression of Speake Marin’s in- depth expertise in the watchmaking art combined with its English roots: the emblematic Piccadilly case, a strong element at the origin of the brand and our latest in-house calibre could not be missing in this collection.


With the Sandblasted Openworked watches, the iconic Piccadilly case, revamped by renowned designer Eric Giroud in 2017, is crafted in polished grade 5 titanium or 18k red gold. It is available in two sizes: 38 mm and 42 mm, with a thickness of 10.5 mm. The dial and the case back are protected by a sapphire crystal glass with anti-reflective treatment.


The sandblasting technique provides a grain finish that, while uniform in texture, appears rough and extremely elegant. The finishing of visible movement parts, the polished beveled profiles of bridges and apertures on the display highlight the decorative complexity executed by our skilled craftsmen. The matt black minute indications and the small seconds counter positioned at 1:30 are applied with an innovative 3D technique.

To ensure optimal legibility and aesthetic harmony, the seconds hand and the heart-shaped central hour and minute hands are polished black on the titanium version while are gold- coated on the red gold variant.


At the heart of the Sandblasted Titanium and Sandblasted Red Gold is the self-winding in- house calibre SMA01. This movement with fully integrated micro-rotor, which allows for a reduced case thickness, was entirely designed and assembled by the well-known workshop “Le Cercle des Horlogers” in La Chaux-de-Fonds. Its 4hz frequency beats at 28,800 vibrations per hour and the single barrel guarantees 52-hour power reserve.

The new SMA01 calibre features exceptional watchmaking decorations visible through the sapphire crystal porthole. From the sandblasted bridges with polished chamfered profiles to the sunray and microbeaded finishes of the oscillating mass, embellished with the brand’s logo topping tool and secured by a bridge with vertical satin finish. Both components feature polished bevelled edges and are gold coated. The high level of attention paid to finishing and decoration also includes the Ø2 mm circular-graining motif on the back of the dial, the engraved values on the barrel, the polished screws, and more.

The engraving on the barrel, clearly visible on the dial side at 5 o’clock, expresses the 8 fundamental values of Speake Marin: RESPECT, INDEPENDENCE, LIBERTE, UNIQUE, AUTHENTICITE, GENEVE, CREATIVITE, MODERNITE.

All of these represent the Maison Speake Marin in the past, present and future of the brand. These words, meaningful and intense, are the very essence of our creations.

Finally, the jewels add a touch of color to the calibre.

Both versions are set with a grey or black leather strap respectively closed by a 18K red gold pin buckle or a titanium folding buckle matching the case materials. Collection available from October 20th, 2023.
