Certina Watches Review: History and Highlights from the Modern Collect Teddy Baldassarre

Certina Watches Review: History and Highlights from the Modern Collect

Certina is a watch brand that may be fairly new to you, especially if you live in the United States, where distribution has been limited to non-existent over the past several decades. In actuality, however, Certina is among the oldest Swiss watch brands currently in operation and today represents an appealing and perhaps underrated option in the arena of stylish sports watches that are solidly built yet priced affordably. The Kurth Brothers, Grana, and the Dirty Dozen Certina has its origins in 1888, when two Swiss brothers, Adolf and Alfred Kurth, set up a watchmaking workshop in an annex to their family home in the town of Grenchen (above). Initially, the brothers made movements and parts that they supplied to other watch companies in the region, but by 1906 they were making enough of their own complete timepieces that they introduced a brand name: Grana, which was a shortened version of the Latin word “Granatus,” referring to Grenchen. The early Grana watches found success, but for several years the Kurth brothers continued to also make and supply movements to other companies; the name “Certina” - another Latin-derived word, from “certus,” for “sure” or “certain” - began appearing on the company’s timepieces throughout the 1930s. The name, which was also easier to pronounce than “Grana” in more languages, was registered in 1933 and eventually became the company’s sole name in 1949.  Few Grana watches are remembered as milestones today, i...

What I Discovered on My Visit to The Aristo-Vollmer Factory

I recently visited the Aristo Vollmer watch and bracelet manufacturer in the Black Forest town of Pforzheim. Aristo-Vollmer was founded 14 years ago as a merger of two well-known companies from the towns of Birkenfeld and Pforzheim. After three generations in the possession of the founding Epple family, the watch manufacturer Aristo Watch was sold in 1998 to Hansjörg Vollmer, a member of the founding family of watch bracelet manufacturer Vollmer, which has been associated with Aristo since 1927. Hansjörg Vollmer is a grandson of the founder of the metal bracelet manufactory Vollmer (Vollmer, Evvo, New Line), which was founded in 1922 and had maintained business relations with Aristo since 1927.  After World War II, the production of bracelets moved from Birkenfeld to Pforzheim where it is still located next to the Pforzheim train station. Since 2005, the Aristo-Vollmer’s portfolio includes watch brands (Aristo, Aristomatic, Aristocrat, Messerschmitt, Vollmer, Bellana, Aristella, and Erbprinz) as well as bracelets (stainless steel, titanium, carbon), buckles, and deployant clasps. The bracelets are used for its own watch brands, and supplied to retailers, as well as outside the group. Recently Aristo added Klaus Jakob’s Jacques Etoile brand, which we’ll come back to a little later. Hansjörg is an intriguing personality, very driven yet approachable. He is a high-speed fanatic and professionally races BMW motorcycles, and even custom builds them upon request. I att...

Trying To Get Airborne With The Rolex Sky-Dweller In Yellow And Everose Gold On A Jubilee Bracelet

Honest question: why do people like the Sky-Dweller? Is it because the travel watch with the Saros annual calendar and Ring Command is a complicated piece of watchmaking? Is it the characteristic dial layout, perhaps? Or is it because if you wear this 42mm watch in precious metal, everybody within a hundred-meter radius will know […] Visit Trying To Get Airborne With The Rolex Sky-Dweller In Yellow And Everose Gold On A Jubilee Bracelet to read the full article.

Hands On: Audemars Piguet Royal Oak Concept KAWS “Companion”

Launched a few months ago, the Royal Oak Concept Tourbillon “Companion” 43 mm is Audemars Piguet’s first collaboration with Kaws, the contemporary artist best known for work inspired by Mickey Mouse and The Simpsons. While the Kaws edition is not the first AP pop culture collab, it is arguably the best. Initial thoughts I like the Royal Oak Concept Kaws, more than any of AP’s other pop culture collaborations. I like the aesthetic, feel, and execution (though not the oversized case), which put this amongst the best contemporary art crossovers in watchmaking. The Hublot-Murakami series is another outstanding artist-watchmaker collab, but the AP-Kaws watch is executed to a much higher level of quality (and price). Visually, the Kaws is big and bold, but rendered in muted, monochromatic grey – a paradoxical but complementary combination. At a distance the watch seems like yet another oversized Royal Oak, but up close it gets more interesting, starting with the fact that it has no hands in the traditional sense. The lack of hands (which are replaced with peripheral pointers) make this a little more interesting, since the cal. 2979 is a new movement that’s a variant of AP’s more conventional tourbillon calibre. I appreciate the fact that the movement was developed for this watch, both in order to accommodate the figure on the dial and to incorporate the “padded” Kaws aesthetic into the movement bridges on the back. Adding a mechanical complication to the Kaws s...

Breitling’s Flagship Navitimer B19 Perpetual Calendar Chronograph in Steel

The flagship watch of Breitling’s best-known watch, the Navitimer B19 Perpetual Calendar Chronograph is now more affordable. The latest iteration with an “ice blue” dial retains the specs of the pink gold 140th anniversary edition launched last year, but trades precious metal for steel. Unlike last year’s limited edition, the new steel model is regular production and is priced under US$30,000, over Breitling’s traditional sweet spot on the price spectrum but still half the retail of the anniversary edition. Breitling Navitimer B19 Chronograph 43 Perpetual Calendar_Ref. PB1920251C1P1_RGB Initial thoughts The new Navitimer B19 keeps it affordable, relatively speaking, by combining Breitling’s excellent in-house B01 movement with the tried-and-tested Dubois Depraz perpetual calendar module. The resulting watch is thick at almost 15 mm high, but combines several complications in Breitling’s iconic slide-rule pilot’s chronograph. While the watch is pricier than most of Breitling’s offerings, it is one of the few perpetual calendar chronographs in this price range. Most of such watches tend to be a lot more expensive, although Austrian independent watchmaker Habring² offers similar for less in keeping with its focus on affordable complications. Value proposition The new B19 retains the same basic specs as its precious metal counterpart. The stainless steel case measures 43 mm in diameter and 14.94 mm in thickness. Water-resistant to 30 m, it features the Navit...

Video Reaction: the Bulova Snorkel Collection

The other day, I got to sit down and take a look at the new Bulova Snorkel collection. They caught my attention for a simple reason: they are literally eye-catching. The brand’s first foray into the new world of “hybrid” ceramics, they bring an unexpected dose of color to a well-liked, if a bit cult, vintage model: the amusingly named “Devil Diver.” In the video below, I go hands-on with this new collection and give you my thoughts on this trend of not-quite-plastic watches and, of course, the Snorkels themselves.

Insight: Regulating a Mechanical Watch Movement SJX Watches

Insight: Regulating a Mechanical Watch Movement

A mechanical watch is not always spot on; less-than-perfect timekeeping can happen, often due to an unruly oscillator. The solution is direct adjustments to the hairspring and balance assembly, either slowing down or speeding up the oscillator, a practice known as regulation. Watchmakers have devised multiple innovations to achieve this, including the free-sprung balance, exemplified by the Gyromax of Patek Philippe and Microstella of Rolex. While a simple concept in principle, the mechanics and practice of regulation are nuanced. Here we’ll delve into the theory of regulation and the primary regulating systems: the curb-pin regulator and the free-sprung (or variable inertia) balance. The Lange L043.4 with a screwed balance inspired by pocket watches Basic concepts In order to better understand watch regulation, we need to first cover some of the basic physics behind the watch oscillator: The component responsible for the running rate of a movement is its regulating organ. The regulating organ is made up of a hairspring paired to a balance, which together are also known as a harmonic oscillator. The natural oscillation period is the time it takes the balance to make a full swing, back and forth. The period is made up of two vibrations, one for each direction of the balance motion, with the escapement being unlocked at each vibration. Notably, the natural period of a balance wheel is intrinsic to itself and does not depend on the escapement type or the going train ratio. ...
