Tudor black bay 54 lagoon — Tudor / Tudor

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.

Zenith Chronomaster original debuts handsome midnight blue dial variant

Vintage modern: Zenith's chronomaster original blue dial honors 1969 a386 legacy

New Chronomaster Original from Zenith

Zenith offers the first blue dial model of its Chronomaster Original, expanding the group that follows the 1969 A386 El Primero. This watch sells for CHF 9,900, EUR 10,400, or USD 10,300. The midnight blue watch combines older looks with the modern El Primero 3600 movement that measures time to a tenth of a second.
The year 1969 made watchmaking history when the first automatic chronograph movement came out. Zenith's El Primero caliber, a fast, complete chronograph, became the first to finish among other makers. The round A386 watch, with its three-color counters, became the brand's main model that showed Zenith's chronograph past.
The Chronomaster Original, which came out in 2021, acts as the A386's real follower, not just a copy. This good mix of old details and new function keeps the small 38mm case size and three-color sub-dials. These parts copy the first sizes while holding the newest El Primero 3600 movement.
The midnight blue dial creates a good blend—it mirrors the blue outer scale, the date window frame, and the date disc for color matching. The blue, grey, and silver counters lie slightly on top of each other. They have a spiral finish that stands out against the sunray-brushed blue dial.
Older style shows through the correct fonts and logos that match the first watch. It also has raised, cut, and lit hour markers. The trapezoid date window at 4:30, the double outer scale, the white stick hands with black parts and glowing material, and the bright red central chronograph seconds hand keep true to its past.
The El Primero 3600 caliber works better than the first movement—it runs at 5Hz. The Chronomaster Original records times to a tenth of a second as the red central chronograph hand goes around every 10 seconds. The first tachymeter scale gives way to precise tenth-second marks on the edge.
Fast work changes sub-dial details, with all counters reading to 60. Small seconds appear in the light grey sub-dial at 9 o'clock. The 60-minute counter sits in the dark grey sub-dial at 6 o'clock. The 60-second elapsed times show in the blue sub-dial at 3 o'clock.
Digital scans of the 1969 watch led case building, making sure of the real 38mm size with a sloped side, sharp cut lugs, pump pushers, and mixed brushed and shiny parts. The very thin edge keeps original sizes. Newer additions include curved sapphire glass on the front and back.
The El Primero 3600 appears through the 12-sided caseback edge. It keeps a column wheel and flat parts while offering a 60-hour power hold and a stop-seconds function. The open rotor shows the new movement's blue column wheel and open bridges.
Each watch has a three-link stainless steel band and a blue calfskin strap with folding locks, offering options for different wearing events.

Citizen launches ATTESA blue universe collection with duratect dlc blue coating

Citizen's ATTESA blue universe collection features innovative surface hardening

Citizen ATTESA blye

Citizen adds two special Blue Universe models to its ATTESA collection. The watches feature a dark blue coating on their bezels and the center links of their bracelets, achieved through an advanced surface hardening method inspired by the colors of the stars. One model is priced at $1,080 and the other at $2,437.
The deep blue color is created using thin film interference, similar to the effect seen on soap bubbles. This coating is not only visually striking but also highly durable, measuring 1,000-1,400HV on the Vickers scale—much harder than standard stainless steel, which is around 200HV. Advanced titanium processing creates a clear contrast between the brushed octagonal bezel and the smooth case lines, with the case and bracelet connecting seamlessly for a clean, professional look.
Both models have black dials with sparkling specks that mimic stars in a quiet night sky. Simple silver-colored hour markers and hands ensure easy readability while maintaining the collection’s celestial theme.

The CC4106-74E, priced at $2,437, is limited to 2,000 pieces and features the F950 caliber with Satellite Wave GPS. This movement maintains an accuracy of ±5 seconds per month without a signal and offers a five-year power reserve on a full charge. Additional features include world time, a 1/20 second stopwatch (up to 24 hours), light level indication, power reserve display, and a perpetual calendar running to 2100.

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.
