Introducing - Henri Grandjean & Cie Unveils the Magician Atrivm Green Sapphire and Atrivm Red Sapphire

Hands-On: The Quietly Launched Jaeger-LeCoultre Reverso Tribute Monoface “Or Deco Cocktail” Hodinkee

Hands-On: The Quietly Launched Jaeger-LeCoultre Reverso Tribute Monoface “Or Deco Cocktail”

Last year's launch of a new Reverso Tribute Monoface "Or Deco" in pink gold (with a gorgeous Milanese mesh bracelet) was probably the most outstanding release from Jaeger-LeCoultre in a while. Its time in the sun was somewhat brief, though, as it was a bit upstaged this year by the new Master Control Chronometre line (for which a Hands-On is forthcoming soon, I promise). Yet, at Watches and Wonders last month, the brand showed it could do more with the "Or Deco" platform, introducing three new Reverso Tribute Monoface Small Seconds "Or Deco Cocktail" watches, including two in a new material. Last year's release is still a stunner. You may have missed these new watches. That's in part because the brand is set to make a more complete announcement in a few weeks, with an immersive pop-up of its "Reverso Stories" series from May 21 to May 31 in the Miami Design District, ahead of the opening of a new boutique there this summer. The idea is to focus on rare pieces, including historic high-jewelry models, and to premiere some new Reverso pieces that play into that concept, including this trio. However, before the watches were shipped to South Beach, we got to see them in New York and get to spill the tea, as the kids say, before their Miami feature debut.  The standouts, at least in terms of novelty, are the two new white-gold versions. The framework remains the same, a 45.6 x 27.4 x 7.56mm case, now in white gold, housing a manually wound Jaeger-LeCoultre caliber 822 movement....

eBay Finds: Solid Gold! Vintage Watches from Omega, Movado, Seiko, and More, Including Some Affordable Precious Metal Pieces

eBay Finds is back! This bi-monthly installment will feature a selection of watches currently listed on eBay that have caught the eye of editor Christoph McNeil (@vintagediver). If you come across any hidden gems on the ‘Bay drop us a note at info@wornandwound.com for potential inclusion. Vintage Omega Seamaster  While the 1950’s “fat lug” Seamasters may be the more well known of the non-diver Seamasters, Omega made plenty of other really nice variations, this one included. The 34mm steel case looks like it has been polished at some point in its life, but not polished to death. This one has a thinner bezel and slim lugs, but these complement the slim applied steel markers and unusual sword hands. The silver/white dial looks original and clean as well. The Omega caliber 591 automatic movement looks good and runs well per the seller. The crown is not original, which is a bummer but not always a deal breaker. The watch does come on an Omega beads of rice bracelet, which may not be original but is definitely period correct. View auction here Vintage Benrus  Here’s a sweet looking vintage Benrus daily watch. Classic 34mm round steel case with simple lugs looks unpolished with sharp edges and original brushed finish on the sides. The silver crosshair dial is absolutely mint, with long, slim hour markers and lume filled dauphine hands. No date window to ruin the beautiful symmetry. The crown is original and signed with the Benrus three-star logo. The watch comes on a ...

Behind the DIN 8330 Standard for Pilot’s Watches

Standards and certifications in watchmaking were primarily developed for chronometry, as well as to reassure the buyer that their watch had been thoroughly tested to a certain level of accuracy. The standards we see most often in the technical specifications are COSC, METAS, and other company or regional chronometry certifications. In modern watchmaking, other key standards like the ISO 6425 dive watch standard, which was developed in the 1990s and followed by watch companies, also come into play. These standards were largely based on various military set standards for watches; however, since each military set their own requirements, there was not one universally followed standard. The International Organization for Standardization (ISO) published specific requirements and testing procedures for a watch to be officially designated a “Diver’s watch”. While there is no ISO standard for pilot’s watches, there are specific requirements set by militaries around the world. One of the most well-known standards is from the WWII German pilot’s watch known as the “Beobachtungsuhren” or “B-Uhren.” B-Uhren pilot’s watch standards are well documented and are still followed by many watch companies to this day. In March 2012, Sinn lead an initiative in collaboration with the Faculty of Aerospace Technology at the Aachen University of Applied Sciences to create TESTAF – Technical Standard for Pilot Watches. TESTAF was developed so that a pilot’s watch meets all mod...
