Commentary
This novelty is a 7 piece celebratory piece for Sincere Fine Watches’ 70th Anniversary. The watch is based on the existing regular Friedrich III line powered Caliber VI movement, but with a remontoir added to the make this the Caliber VI-I. The movement is spectacular, as usual. With the plates and movement bridges which are finished in fine graining with beautifully executed anglage on the edges.

We first saw the remontoir introduced by Lang & Heyne in the Lavish Attic Edition of the Friedrich III. The Lavish Attic Edition also had the Caliber VI-I , but worth the movement in titanium. This Sincere Edition novelty release documentation does not state the material of this movement, but it looks like a standard brass movement with the usual (very nice!) haute horlogerie embellishments.

The remontoir is a device which is fitted between the power train and the escapement to moderate the force from the mainspring. This mechanism is visible as a wheel with its own small spring and escapement system coaxial mounted above to the fifth wheel. It takes power from the mainspring to wind its own remontoir spring which is used to power the fifth (escape) wheel. Thus, the watch’s escapement is powered by this remontoir spring, and not the mainspring. This ensures a more constant force being delivered to the escapement by virtue of its smaller size. The remontoir has its own escapement system and is re-wound every second by the fourth wheel, which moves one position every second. As the seconds hand is mounted on the fourth wheel’s axel, the watch performs a jumping seconds action.

What is also new is the dial. Instead of a massive silver dial which is the norm for Lang & Heyne watches, the Friedrich III Remontoir Sincere Platinum Jubilee Edition uses a ceramic dial with a sand blasted blue silver decorative center medallion.

Ceramic is not a typical material used for dial making, and certainly not traditional. This is an interesting selection of material for the dial. The subsidiary seconds sub-dial is made from a separate ceramic disc merely 0.4mm thick. This is friction fitted on a cutout on the main ceramic dial, and is subtly sunken. This sunken sub-dial is a traditional styling often seen in vintage pocket watches with enamel dials, but is seldom done these days because of the technical challenges required to execute it perfectly. And certainly the first we have come across with a sunken ceramic sub-dial fitted into a ceramic ring with a solid silver center. The dial looks spectacular, with the beautiful interplay of the colours and textures being a defining character of the dial.
As this article is being published, we are in discussion with Alexander Gutierrez Diaz, CEO of Lang & Heyne, and Jens Schneider, watchmaker. We will have more clarity on the parts which the release is not clear and will report back soon.
Release details
Commemorating Sincere Fine Watches’ 70th Anniversary, Lang & Heyne proudly introduces the Friedrich III Remontoir Sincere Platinum Jubilee Edition, limited to 7 pieces. As a valued partner, Lang & Heyne was among the three distinguished manufacturers to launch the inaugural SHH Editions at the opening of Sincere’s concept boutique, SHH (Sincere Haute Horlogerie), in Singapore back in 2022. This enduring collaboration is again showcased as Lang & Heyne and Sincere Fine Watches collaborate to present the latest Sincere Platinum Jubilee Edition.

Located in Dresden, Germany, Lang & Heyne is renowned for crafting exquisite timepieces from the finest materials. Each piece exemplifies extraordinary craftsmanship, intricate design, and meticulous attention to detail. The production process demands exceptional skill and expertise, from constructing movement components, hands, and cases to their refined finishing. Lang & Heyne’s dedication ensures unparalleled finesse in both aesthetics and functionality.

The Lang & Heyne Friedrich III Remontoir Sincere Platinum Jubilee Edition features a ceramic dial with a sand-blasted royal blue silver decorative plate at the center.
The Friedrich III Remontoir Sincere Platinum Jubilee Edition distinguishes itself from the current collection, with its unique dial design. Unlike the conventional solid silver dials, this edition features a ceramic dial with a sand-blasted royal blue solid silver decorative plate at the center. The interplay of colors and textures, highlighted by the frosted givree-finished blue center against the smooth white ceramic periphery and seconds subdial, adds depth and character, enhancing the dial’s captivating appeal. The Lang & Heyne Friedrich III Remontoir Sincere Platinum Jubilee Edition employs a three-part dial concept, where the seconds subdial sits lower than the main ceramic dial and royal blue silver decorative plate.

The Sincere Platinum Jubilee Edition draws striking parallels with the inaugural Lang & Heyne Georg SHH Edition launched in 2022. It features a similar combination of materials, colours, and finishing techniques on the dial and employs the same three-part dial concept. The seconds subdial, measuring just 0.4 mm thick, sits lower than the main ceramic dial and royal blue silver decorative plate at the center, precisely fitting into the baseplate’s recess with sanded outer contours. Chamfered and polished edges enhance the dial’s sophisticated, three-dimensional appearance. Limited to 7 pieces, this timepiece pays homage to the Georg SHH Edition while asserting its uniqueness within the collection, making it a fitting tribute to Sincere’s Platinum Jubilee celebrations.

EMBODYING TIMELESS ELEGANCE AND REFINED AESTHETICS
The harmonious combination of decentralized seconds, numerals, and hands creates a visually pleasing and functional ensemble for the Friedrich III Remontoir. The distinctive trigonal bridge is a standout feature of the Caliber VI-I movement architecture, revealing the meticulously crafted gear train beneath.

The Caliber VI-I movement is distinguished by its exceptional finishing across its components and meticulous hand engraving performed by skilled craftsmen. The baseplate is intricately engraved with ‘One of 7’, underscoring the exclusivity of the Sincere Platinum Jubilee Edition. On the open caseback, Sincere’s 70th Anniversary logo is elegantly engraved on the sapphire glass paying homage to the occasion. The balance cock features an intricate pattern, meticulously etched to further enhance the aesthetic of the movement. Found beside the escape wheel of the Caliber VI-I, the remontoir complication enables a smooth and efficient transmission of power for the Lang & Heyne Friedrich III Remontoir Sincere Platinum Jubilee Edition.

REMONTOIR COMPLICATION
Lang & Heyne watchmakers’ dedication to precision and craftsmanship has contributed to the smooth and efficient power transmission of the movement. Positioned beside the escape wheel of the Sincere Platinum Jubilee Edition, the remontoir complication provides the visual appeal of the jumping seconds on the dial while effectively regulating and controlling the mainspring, resulting in a consistent transfer of energy across the entire power reserve of the timepiece.

The Remontoir operates by incorporating an intermediate energy accumulator that is regularly re-tensioned by the movement of the gear train. When the primary energy source – the mainspring, transfers its energy to the watch’s wheel chain, the Remontoir’s locking mechanism temporarily halts this energy flow, redirecting it into an intermediate spring. This intermediate spring then powers the remaining gears up to the escapement, which regulates timekeeping.A control element moving with the gear train activates the locking mechanism at regular intervals, ensuring a steady and precise release of energy. This process not only keeps the watch running smoothly but also results in a jumping seconds display on the dial.
Designed with timeless elegance in mind, the Friedrich III Remontoir Sincere Platinum Jubilee Edition features a dark blue Alligator Mississippiensis leather strap, known for its durability and flexibility.
Recognized for its enduring quality, this strap accentuates Lang & Heyne’s commitment to authenticity and functionality.
A fusion of aesthetics is evident in this timepiece, featuring rare cathedral design polished steel hands and a domed crown. Reflecting its prestige, the timepiece utilises 18-carat white gold in both the case and the pin buckle – the ideal material to for a prestigious and refined timepiece like the Friedrich III Remontoir Sincere Platinum Jubilee Edition.
