Diamond Plate Progression
Some counterintuitive findings from The Science of Sharp, analyzing the cutting surface of straight-edge razors honed on varying grits of DMT diamond plates. "Often, results that contradict our intuitive expectations are a key to identifying and improving our deficient understanding."
I use DMT diamond plates to hone the gravers I use with my watchmaking lathe. Anecdotally, I find that finishing to a mirror polish using the extra-extra-fine diamond plate yields an appreciably better finish when turning down a pivot or an arbor. I'd love to see a similar set of SEM images run on a watchmaker's graver, which would be less prone to the plastic deformation conjectured through these results.
ArtyA Purity Tourbillon
The movement architecture of ArtyA's latest tourbillon is aesthetically well-balanced. With respect to the balance itself, I applaud the use of a free-sprung balance wheel—any tourbillon without a free-sprung balance, isn't taking itself seriously. I do have some concern about the one-to-one ratio of the gear train delivering power to the tourbillon itself, though.
Rolex USA Provides Official Comment on Yahoo! News Story Regarding Supply
It's worth noting that this comment is from Rolex Watch USA Inc. & not from Rolex SA. While a good degree of care clearly went into this response & the reasons provided are both sound & in line with the brand's values, the official comment itself lands a stride short of the excellence that Rolex SA is renowned for.

A Clinic on Your Wrist
Apple supplier, Rockley Photonics, announces clinic-on-chip technology that includes non-invasive blood glucose monitoring.
The inclusion of the Marc Newson strap design in the press release—a hallmark of the Apple Watch since its unveiling—is a clear nod at whose "scalable, high-volume product delivery" pipeline their infrared spectrophotometer tech is headed for.
“I’ve Discovered That You Work Metal Like Wood, Metal Is Fibres.” – Denis Flageollet
Leveraging tech from big brother, Omega, & sister brand, Rado, it's nice to see Tissot rolling out more & more ceramic bezels throughout its line-up.
Coupled with their new free-sprung balance & silicon hairspring, Tissot is serving up incredible value in the sub-$1000 mechanical watch category.
What Does It Take to Hear Big Ben Again?
Working from a covert location, Ian G. Westworth is among the 500 workers who have been busy restoring Elizabeth Tower, Big Ben, & its Great Clock, “It’s a real honor. There are very few people who can say they’ve taken the Great Clock of Westminster apart & put it back together again."

A Nivarox Branded Observatory Competition Peseux 260 From the 1950s
Today Nivarox operates largely behind the scenes, supplying the beating heart inside the vast majority of spring-powered Swiss timepieces, from Swatch to Patek Philippe. The low escape wheel in this caliber allowed for a larger balance wheel & thus better rate stability. Kari Voutilainen later employed the Peseux 260 in his series of Observatoire timepieces, which were awarded certificates of chronometry from Besançon Observatory.
40Hz Silicon Oscillator
While I have a deep appreciation for bi-stable mechanisms & admire the pioneering work Flexous has achieved with this new oscillator & escapement for Frederique Constant, I think it's a mistake to show it off through an aperture in the dial.
There is something humane & almost soothing about watching a mechanical timepiece tick away at rate of five to eight times per second. Witnessing the oscillator vibrating a literal order of magnitude more than that every time you look at your wrist is going to feel downright unnerving.
