3 Reasons The Rolex Day-Date 40 Convinced Me: A Very Rolexy Rolex Discussion

Rolex had never called out to Joshua Munchow as a watch that he must have or that would be the pinnacle of his collection. He thinks that this is because of the downsides to it being the most widely known watch brand in the world: forgeries and overexposure abound. So what is it about 2015's Rolex Day-Date 40 that turned him into a convert? Read on to find out.

Insight: The Geometric Efficiency of Escapements SJX Watches

Insight: The Geometric Efficiency of Escapements

Mechanical escapements remain the most fascinating and enticing field of horological study even in the 21st century. At its core, an escapement has a simple purpose: restore lost energy to the oscillating organ while regulating the discharge speed of the going train – thus allowing for time measurement. Straightforward as the concept is, executing an escapement well is a completely different affair. The escapement is perhaps the element of the mechanical movement that has undergone the most iterations since its invention. The reason is simple: escapements were, and remain, imperfect systems. In fact, the escapement is often the least efficient aspect of a mechanical movement in terms of energy transfer. That’s why watchmakers and engineers have devised innumerable variants in the search of the ideal escapement.  Explaining escapement efficiency In physics the efficiency of a system is the proportion of useful work done relative to the total work done by said system. The result, measured as a percentage, speaks to the energy conserved within the system. For example, an 80% efficiency means that 20% of the total available energy is lost, with the remaining 80% usefully conserved.  That said, an efficient escapement isn’t necessarily chronometrically-potent, since there are more criteria, apart from energy conservation, which reflect in a movement’s accuracy. The way in which escapement parts impulse to the balance, the proximity of the equilibrium point and the deg...

Hands-On With The Beaufort Pulsatimer - A Brawny Blend Of Retro Delights And Tool Vibes

I’m all for a tough sports watch with a muscular design accompanied by a matte black or blue dial, a solid depth rating, and big, blocky lume-printed indices. But the Beaufort Pulsatimer is a conflicting mix of this and dressy vintage, and it frazzled my watch-brain neurons. I have a confession to make: sometimes a […] Visit Hands-On With The Beaufort Pulsatimer - A Brawny Blend Of Retro Delights And Tool Vibes to read the full article.

The Watch I Didn’t Buy: Crossing Financial Thresholds Two Broke Watch Snobs

The Watch I Didn’t Buy: Crossing Financial Thresholds

Watch budgeting is a funny thing. For most collectors, it involves a significant amount of mental gymnastics as money is moved in and out of an imaginary bank. We say things like “sorry, no funds in the watch bank” when our friends are selling a watch we don’t want to buy. But when Jomashop is offering a deal on that Seiko we’ve been lusting over, funds are magically ready for immediate withdrawal. Sometimes this is because we’ve recently sold some watches and actually have a positive balance in the watch bank. But often, we buy that new Seiko on “credit” with a self-promise to liquidate the current collection to restore financial balance.

Bulova Precisionist: The Most Underrated Movement in the Watch Industr

Newcomers to the watch appreciation game can be forgiven for reflexively, and solely, crediting the Japanese with bringing electronics into the mainstream of the watch industry, but the embryonic phase of the technology took place in the United States. And the most accurate electronic movement on the market today emerged from the synergy between one of America's most historic home-grown watch manufacturers and one of Japan's most innovative pioneers of timekeeping technology. It's called the Precisionist, it's exclusive to Bulova, and while you may not have heard of it or know much about it, it's becoming a fixture in several Bulova watches that increasingly demand enthusiast attention. Bulova, founded in New York City in 1875 by Bohemian immigrant Joseph Bulova, was one of the first watchmakers in the world to seriously explore the development of electronics in wristwatch movements. In 1960, just a few years after another American watch manufacturer, Hamilton, had introduced its flawed but groundbreaking electric-powered Ventura (more on that here), Bulova unveiled its own high-tech timepiece, the Accutron Spaceview 214. The watch took its numerical designation from its movement, Caliber 214, a revolutionary mechanism in which the balance wheel, which drives the timekeeping in a mechanical movement, was replaced by a tuning fork, powered by a one-transistor electronic oscillator. This system ensured an oscillation rate of 360 hertz - nearly 150 times faster than tha...
