Fittingly for a watch with equestrian origins, the pink […]

Introducing: The Organic Shades Of The Panerai Radiomir Bronzo PAM00760

Panerai has introduced the PAM00760 as a bronze take on the Radiomir, celebrating the 90th anniversary of the Bermudian ketch Eilean. The new Radiomir Bronzo keeps things simple on paper, with a hand-wound movement, a two-hander layout, and a familiar 47mm case, but its appeal lies in its use of color and texture.

Interview: Zenith’s Product Chief Officer on Reviving the Chronometer Cal. 135

For much of the past quarter-century, Zenith has built its brand on the back of the El Primero — a fast-beating chronograph calibre that debuted in 1969. But last year — for its 160th anniversary — the brand revived the time-only calibre 135 – a legendary competition calibre originally developed in the late 1940s. The reborn movement debuted within a new collection — the GFJ — named after founder Georges Favre-Jacot. To better understand what lies behind the relaunch of the cal. 135, we talked to Romain Marietta, Chief Product Officer at Zenith. David Serra, Technical Director of Movement Development, provided additional production insights. As Mr Marietta explains, the relaunch of the cal. 135 opens a new chapter for Zenith — more exclusive and more artisanal, featuring precious materials, elevated finishing and a classical aesthetic inspired by the designs of the 1950s. In short, closer to the independent watchmakers’ approach and to their audience. And this is only the beginning — the Le Locle-based brand has plans to further develop both the calibre and the collection. The interview was edited for length and clarity. Yannick Nardin (YN): Let’s start at the beginning: what makes cal. 135 so special? Romain Marietta (RM): For context, it was produced from 1949 until 1962. At the time, the pursuit of precision had a real genuine meaning. Watchmakers measured their strength, stature and reputation through the prizes they won. This movement was created f...

Panasonic’s L10 camera honors 25 years of Lumix This year, Japanese brand Panasonic celebrates their 25th anniversary of their brand of digital cameras, Lumix, with the release of the L10. In the past quarter of a century, the brand has done the remarkable job of positioning itself as one of the premier camera brands on the block – and it shouldn’t go unnoticed how tough this is with competitors like Leica, Sony, and other household names.  And now that Lumix can legally rent a car, their L10 is a bit grown-up, and a bit back-to-basics (in the best way possible). This compact camera leans into a more tactile shooting experience, with a clean body design, physical controls, and a hybrid setup that works for both stills and video. It features Panasonic’s latest autofocus system, built-in stabilization, and high-resolution video recording, giving it enough technical specs without becoming unwieldy in features – or, for that matter, design. The Lumix L10 is slated to launch in June with a price tag of $1,499 in black or silver, with a special edition gold titanium model also available in limited quantities for $1,599.  FieldMade Blackout Stealth Kits for Leica ...

Micromilspec And Black Badger Team Up For The Adventurous Broken Hour

Early last year, Micromilspec teamed up with James Thompson, aka Black Badger, to release the Micromilspec Milgraph Sabotage Edition.

The Arken Alterum Returns to the Internet in Sage Grey Worn & Wound

The Arken Alterum Returns to the Internet in Sage Grey

Arken, the UK based microbrand founded by Kenneth Lam, is back with a new version of their Alterum model in a Sage Grey colorway. The Alterum has been a tough watch to catch since its introduction in 2023. The first batch of 200 sold out quickly, as did a subsequent run. For the last year or so, Lam has been focused on getting out to watch events and showing people the Alterum in person, offering secret “Speakeasy” versions of the watch made just for those events (no photographs, please). So, a new version of the Alterum that you can actually order on a website is a bit of a novelty in and of itself, and for folks that haven’t been able to make to a show where Arken has been in attendance, or just would prefer this particular dial execution, now is the time to mark those calendars.  We covered the Alterum here, but a quick refresher is likely in order for anyone not familiar with the watch’s unique mechanical footprint. It’s a two timezone watch, with a module built on a Miyota movement of Lam’s own design. That module allows for the tracking of day and night in two time zones and the independent setting of the local time by “locking” the GMT hand when rotating the crown counterclockwise.  I’ll be honest here: setting the Alterum is kind of complicated. I’m an owner of an Alterum, and I still don’t quite get it myself. I have the local time set to my own time zone on the east coast of the United States, and the GMT hand permanently set to “Ken tim...
