Collector Guide

The Explorer II collection traces its roots back to 1971, when Rolex designed a watch specifically for cave explorers and adventurers operating in total darkness.

The reference 216570 continues that legacy with modern engineering and enhanced usability. Its defining feature—the fixed 24-hour bezel paired with an orange GMT hand—allows wearers to distinguish between day and night, even without natural light.

While originally intended for extreme environments, this functionality has evolved into a practical feature for modern travelers, offering a second time zone at a glance.

One of the most significant updates introduced with the 216570 was its larger 42mm case, a first for the Explorer II line.

This increase in size was more than aesthetic. It brought:

• Improved legibility through a “maxi dial” with larger hour markers
• A stronger wrist presence compared to earlier 40mm references
• Enhanced proportions to accommodate updated hands and movement

Despite the increase, the watch retains the balanced ergonomics Rolex is known for, making it suitable for daily wear.

The Iconic “Polar” Dial

The white dial variant—nicknamed the “Polar” Explorer—has become one of the most recognizable configurations in Rolex’s lineup.

Its appeal lies in contrast and clarity:

• Crisp white background
• Bold black hour markers and hands
• Striking orange 24-hour hand

This high-contrast design ensures exceptional readability, further enhanced by Rolex’s Chromalight lume, which emits a long-lasting blue glow in low light.

Ebel: Swiss Elegance Meets Architectural Timekeeping

When exploring the world of Swiss luxury watches, one name that stands out for its unique design DNA and rich heritage is Ebel — a brand that blends technical precision with timeless style. Founded in 1911 in La Chaux-de-Fonds, Switzerland by husband-and-wife team Eugène Blum and Alice Lévy, Ebel quickly established its identity by harmonising engineering excellence with elegant aesthetics.

🇨🇭 A Century of Watchmaking with Soul

The name Ebel itself is an acronym — Eugène Blum et Lévy — reflecting the partnership at the core of its creation. Eugène focused on the technical side while Alice guided the visual identity, resulting in watches that were both reliable and visually compelling from the very beginning.

Over the decades, Ebel built a reputation not just on technical expertise but on creativity. It produced watches for Cartier, contributed to timepieces for the British Royal Air Force during WWII, and later designed watches that grabbed global attention.

🌊 Iconic Design: The Wave Bracelet & Architectural Lines

One of Ebel’s most distinctive contributions to watch design is the wave-style bracelet — introduced in the late 1970s as part of the Sport Classic line. This bracelet, with its flowing, interlocking links, is instantly recognisable and remains a signature hallmark of the brand.

But Ebel’s design philosophy goes beyond a single feature. Known as the “Architects of Time,” the brand approaches each watch much like an architect would a building — balancing proportion, form, and detail to create timepieces that feel at once modern and timeless.

Opal is a precious gemstone known for its stunning and unique play of color, which makes it unlike any other gem. Unlike most gemstones, opal doesn’t have a single crystalline structure; instead, it’s made of tiny spheres of silica that diffract light, producing flashes of multiple colors called “play-of-color.” No two opals are exactly alike — every stone has a completely unique pattern and color display, which is why they’re so special in luxury watches and jewelry.

Opal is a natural gemstone, meaning no two dials are ever the same. The play of colour — from soft pastels to deep blues and greens — changes with the light, making each watch unique. Piaget has embraced opal (along with other hard stones like jade and lapis lazuli) since the 1960s, weaving its beauty into both vintage and modern collections. 

This tradition of using stone dials isn’t just about aesthetics — it’s a hallmark of Piaget’s dedication to craftsmanship. In the 1960s and 1970s, the maison pioneered the use of ultra‑thin movements paired with delicate hard stone dials, a bold move at the time that helped define its identity as a maker of elegant, artful watches. 

The Tudor Ranger has roots in Tudor’s long history of rugged, expedition-ready watches. Inspired by timepieces used in adventurous settings — from polar explorations to desert endurance races — the Ranger family perfectly expresses the idea of a field watch meant for real life, not just display.

What makes the Ranger “classic” is its clear dial layout with bold Arabic numerals at 3, 6, 9 and 12, paired with simple batons for the other hours. This layout ensures legibility in seconds — a hallmark of tool watches developed for explorers and professionals.

The Tudor brand takes its name from England’s Tudor dynasty, one of the most powerful and dramatic royal houses in history. Kings and queens like Henry VIII and Elizabeth I symbolized authority, ambition, and endurance—qualities that Tudor sought to translate into watchmaking.

Early Tudor watches even featured the Tudor Rose, the emblem of the Tudor monarchs, on their dials and case backs. This wasn’t just decoration; it was a statement of identity. Tudor watches were meant to carry royal DNA while standing up to real-world use.

The Tudor Royal Collection: A Modern Crown

The Tudor Royal line comes closest to the idea of a true “monarch watch.” With integrated bracelets, notched bezels, and day-date complications, these watches evoke the formality and confidence of royal dress—without feeling outdated.

They’re versatile enough for daily wear but refined enough to feel ceremonial, making them ideal for those who want a watch that quietly commands respect rather than demands attention.
