ETERNA WATCHESSwiss Advertising Poster (27.5" x 39")Fine Folded; Artist Fred Dubois C.1930sThis simple yet effective vintage 1930s Art Deco advertising poster for the luxury watch company Eterna is unique in that even though the poster itself is Swiss, the artist Fred Dubois is French and the poster is a German language version. This poster has had some light restoration work to both folds and some tears. But there is still both edge and fold wear, including small tears and tanning. A piece that is a perfect candidate for linen backing. The Swiss luxury watch-making company that would become Eterna was founded in 1856 by Dr. Joseph Girard and Urs Schild to hand-manufacture the inner workings of watches. Due to this modernization, the company found itself at the forefront of watch development, patenting its first alarm wristwatch in 1908, the first of many innovations it would introduce during its lifetime, including an eight-day watch in 1929 and the first affordable self-winding watch, released in 1948.

He designed his first yacht the Borsalino Trois in 1974, before he'd left college. He went on to design yachts for The Admiral's Cup, which included Vanguard in 1977, and Police Car, which won the regatta in 1979. During the 1980s and 1990s Dubois applied the design and technology behind sailing yachts to his designs for ocean going superyachts of which he designed more than 70. His ground-breaking designs for superyachts included Aquel II, Imagine II, Esprit and Espada.  Condition Report: Movement is currently functioning.

Grottendiek Bruxelles 9422. Ticking, striking, repeating, and alarming, with a later double ended winding key and numbered (9422) leather travel case with purple velvet interior. 19 cms (7 ins) highFootnotes:François Charles Grottendieck was born in 1834 in Saint Anna, Hannover. His father was Ferdinand Henri, a wholesaler, and his mother was Marie Marguerite Wilhelmine Kruse. In 1863 he was married in Brussels to Eugènie Adélaïde Josephe Henriette, who was four years his senior and also a wholesaler. He is listed on his marriage certificate as a horologist, though it is not known where he served his apprenticeship. The couple appear to have gone into business together; given their backgrounds it seems likely that Eugènie would have managed the running of the shop, while Charles would have focused on repair and possibly finishing/manufacture. Throughout the 1860's-70s there was a horologist by the name of Dessaint-Plet whose shop was based at 10 Montagne de la Cour, Brussels. Plet had taken over the shop from another well-regarded horologist, A. Demeur, who is known to have sold carriage clocks by Paul Garnier. Demeur was also horologist to the King of Brussels, a title Plet seemed to receive with the shop. It is unclear when Plet retired, though it appears that Grottendieck became his successor, both to the shop and the title of horologist to the King and Queen of Brussels. It is unknown how long Grottendieck remained at this address, however, by 1901 the Grottendiecks were operating out of a shop on 80 Rue de la Madeleine, and also living above the shop. This may suggest that they had formally relocated from 10 Montagne de la Cour, rather than working out of both shops.In early August 1901, the shop was burgled, the thieves making off with 100,000 francs of items. This included 100 watches (valued between 100-1,500 francs), 30 gold chains (valued at around 10,000 francs), and 15 diamond and ruby trimmed bracelets (valued between 12 to 15,000 francs). Reportedly, Eugènie came downstairs to open the shop around 6.00, and noticed that one of the windowpanes, normally located 1.6m above the ground, had been removed and left on the shop counter. It was later suggested that the thieves climbed onto the arm of a streetlamp in front of the store, which allowed them to access the first storey window. As the lock was still bolted on the door, it appears the thieves left in the same fashion. Finding the shop had been ransacked, she apparently called up to Charles, who helped her draw up a list of missing inventory, before the police were informed. During questioning, it came out that a customer had come into the shop the previous day and spent ½ hour looking at a pocket watch chain. He left without buying anything, and 15 minutes later two different men came into the shop, looked at the same chain for ½ hour, then also left without making a purchase. These men, the first being identified as French, and the other two identified as Dutch, were listed as the likely thieves. It seems there had been a false alarm in the middle of the burglary, as 40,000 francs worth of jewellery had been left on the shop counter. More chillingly, in the room next to the shop, police discovered a dagger and several lengths of rope hastily left on a table. It does not seem that the perpetrator(s) was ever discovered.Charles and Eugènie had at least three children; Frédéric Jacques Joseph (born in 1865), Paul Désiré Joseph Charles (born in 1869) and Emma Ferdinande Joséphine (born in 1871). The eldest, Frédéric, became a horologist, likely being apprenticed to his father. He married Marie Colette Eugénie Briers in Elsene in 1904. Emma married into a family of wholesalers in 1893, both her brothers serving as witnesses. Interestingly, her husband, Paul Justin Louis Joseph Henriette, would serve as a witness to Frédéric's wedding nine years later.Paul Grottendieck became an engineer in Hainaut, at some point marrying Emma Celeste Louise Dubois. The couple had at least one child, Germaine Charlotte Clotilde Grottendieck, born in 1895, who apparently became an internationally lauded cellist. de Caluwé, J. (2019).

The prototypes were promising and the newly named Calibre 11 'Chronomatic' movement; a symbiosis between 'chronograph' and 'automatic' exceeded all expectations.

The prototypes were promising and the newly named Calibre 11 'Chronomatic' movement; a symbiosis between 'chronograph' and 'automatic' exceeded all expectations.This Chronomatic is a very rare example of the first usage of the Calibre 11. One of the hallmarks of the early iteration is the instantaneous calendar which was later modified. Originally it used so much power it could stop the watch when it was wound down. Another is the almost industrial finish to some of the levers and shaky engraving on the signature plate.There are less than 10 that have appeared on the market and it was possible it was produced mainly for the press as almost a prototype. As the dials are prone to flaking, the originality of the lume plots and condition overall makes this example which is in good condition very rare indeed.This lot is subject to the following lot symbols: ΩΩ VAT on imported items at the prevailing rate on Hammer Price and Buyer's Premium.For further information on this lot please visit Bonhams.com
