Piaget introduces obsidian-dialed polo perpetual calendar watches

Stone and steel: piaget crafts obsidian-dialed polo perpetual calendars

Piaget polo perpetual — Piaget

Piaget added two new models to its Polo perpetual calendar collection. Both display natural obsidian stone dials in striking blue and green shades.

The latest models of the well-known Polo line, which began in 1979, continue the company’s tradition of combining ultra-thin mechanical expertise with special material craftsmanship. The volcanic stone dials give each watch a unique character, as the natural shine produced when mineral-heavy sulfides are trapped in fast-cooling lava ensures that no two watches are the same.

Both models come in 42mm stainless steel cases that showcase the Polo’s signature shape-in-shape design-a round bezel set on a cushion-shaped case. The watches offer 30 meters of water resistance, despite their luxurious appearance.

Inside each watch is the ultra-thin caliber 1255P automatic movement, only 4mm thick, which provides full perpetual calendar functionality. The movement displays day, date, month, and moon phase. The moon phase is positioned at 6 o’clock and will remain accurate for over a century without adjustment.

The obsidian blue version has a more understated look, with its deep blue stone dial and a matching rubber strap. The case features both polished and satin-brushed surfaces for added visual contrast.

For extra distinction, the obsidian green model is limited to just 18 pieces. This version elevates the luxury factor, with a bezel set with 56 brilliant-cut emeralds surrounding the natural green obsidian dial.

These stone-dialed models follow Piaget’s 2023 limited edition, which reportedly sold out quickly. This continues the company’s focus on expanding its technical prowess while maintaining its unique design language, as seen in recent releases like the Polo Tourbillon Moonphase.

The price for the obsidian blue model is €108,000. The gem-set, limited-edition obsidian green model is priced at €149,000-placing these watches firmly in the high-end segment of the sport-luxury category, where Piaget continues to showcase its expertise and creativity with materials.

Jaeger-LeCoultre introduces Polaris Chronograph in signature ocean grey lacquer

Lacquer mastery: Jaeger-LeCoultre's polaris chronograph features 35-layer ocean grey dial construction

Jaeger-LeCoultre Polaris Chronograph

Jaeger-LeCoultre adds a new chronograph to its Polaris collection, featuring the brand’s Ocean Grey lacquer dial. This dial is built with impressive complexity: 35 layers of lacquer are applied by hand, with three different finishes giving it depth and character. The 42mm sports watch continues the approach the collection began in 2018, redefining what a modern, sporty, and chic timepiece can be.
The Polaris collection pays tribute to Jaeger-LeCoultre’s diving watches from the 1960s, taking their athletic spirit and translating it into a refined, contemporary design. The Ocean Grey version keeps the line’s signature elements—straight lines, curved lugs, a thin bezel, a glass box crystal, and a mix of brushed and polished surfaces. The large crown and pushers are inspired by the original 1960s model, making them practical and easy to use.
The Ocean Grey dial itself is a showcase of craftsmanship, with a central disc, a middle ring for the hour markers, and an outer ring displaying a tachymeter scale. Sunray brushing on the central disc subtly contrasts with the polished hour ring, while the gradual color shift from light to dark adds visual depth across the dial.
Creating the dial requires meticulous handwork. It starts with a clear varnish base coat, followed by four layers of color and a black layer to create the gradient. Achieving a consistent gradient across the dial’s two main sections is a challenge, and then 30 more transparent lacquer layers are added to create the final sense of depth and richness.
The chronograph’s layout is designed for clarity. A central seconds hand provides precise measurement, with a 30-minute counter at three o’clock and a running seconds subdial at nine o’clock. Circular graining adds visual texture, contrasting with the polished central disc and the textured hour ring. Orange accents highlight key indicators and add a dynamic touch to the overall look.
Inside, the automatic Caliber 761 is Jaeger-LeCoultre’s in-house chronograph movement, combining technical performance with mechanical elegance. Two barrels power the column wheel chronograph with a vertical clutch, offering a 65-hour power reserve. The movement is finely finished, with blued screws, Côtes de Genève decoration, and an open-worked rotor bearing the ‘JL’ logo.
The entire movement is designed, produced, and assembled in Jaeger-LeCoultre’s Manufactory in Switzerland’s Vallée de Joux, making it a true in-house creation. The sapphire crystal case back reveals the movement and maintains 10-bar water resistance, ready for adventure.
The watch offers versatility with two strap options: a blue-grey canvas and a textured black rubber strap. An interchangeable folding buckle system makes it easy to switch straps, allowing the watch to adapt from casual elegance to active sports use.

Tudor introduces Black Bay 54 in lagoon blue with refined aesthetic

Summer vibes: Tudor's black bay 54 lagoon blue transforms heritage dive watch aesthetic

Tudor black bay 54 lagoon

Tudor adds "Lagoon Blue" to the Black Bay 54 collection. This new model transforms the dive watch, which took ideas from old watches, into a refined timepiece that anyone can wear—it fits beach life and summer activities perfectly. The watch costs $4,350. While the new color keeps the 37mm size, it completely changes how the watch looks.
The Black Bay 54 "Lagoon Blue," reference M79000-0001, keeps the original’s 37mm diameter and 11.2mm thickness—ensuring the watch wears well on a wide range of wrist sizes. Tudor has changed up several parts of the design, creating a softer, more current look for their smallest dive watch.
The biggest change is on the rotating bezel. Instead of the old black anodized aluminum insert, there’s now a mirror-polished steel bezel. The steel features a sandblasted 60-minute timing scale, and this polished surface matches the updated hands and hour markers. These now have mirror-polished frames containing white Grade A Swiss Super-LumiNova, replacing the previous gold finish.
The pale blue dial, with its grainy texture, gives the model its "Lagoon Blue" name. This color joins a wave of recent watches using similar "Tiffany blue" tones across the industry. Tudor itself offered a similar shade on the Black Bay Chrono "Flamingo Blue" earlier in 2025. It’s clear the market wants this look, even if plenty of brands are offering it.
Tudor also changed how the watch connects to the wrist. The "Lagoon Blue" comes only on a five-link stainless steel bracelet with polished center links, which is different from the original BB54’s three-link rivet-style bracelet. That older bracelet was a nod to Tudor Submariners from the 1950s. The new five-link design highlights the watch’s modern direction and keeps Tudor’s T-fit clasp for easy adjustments.
The Caliber MT5400 automatic movement stays the same—it offers a 70-hour power reserve and COSC chronometer certification, along with Tudor’s own accuracy standards of -2/+4 seconds per day. While it doesn’t have the METAS Master Chronometer certification found on some new Tudor models, the movement is still perfectly suited to the watch’s purpose.
Tudor’s advertising highlights the "Lagoon Blue" as a watch for a gender-neutral beach lifestyle. It’s not aimed at collectors who chase vintage-inspired pieces—just like Tudor did with the Black Bay 58 Burgundy and solid gold models. This shows Tudor’s move away from strictly history-inspired watches, aiming for a broader, more current appeal.
The $4,350 price is a small increase over the black dial bracelet version, reflecting the more complex five-link bracelet and improved finishing details. Even so, the watch is still reasonably priced within Tudor’s dive watch range.
