The Rolex Explorer, a watch steeped in history and synonymous with mountaineering prowess, has seen several iterations throughout its lifespan. Among the most discussed and sought-after are the 39mm models, specifically the Mark I (Mk1) and Mark II (Mk2) – representing distinct eras and subtle yet significant design changes. This in-depth comparison will delve into the nuances that differentiate these two exceptional timepieces, exploring their design, features, and overall appeal, aiming to assist prospective buyers in making an informed decision.
IMO the 39mm was the perfect size for the Explorer here in the 20's. When it was first launched in the 50's the 36mm was considered large, almost comically so. But here today in a world where 36mm is a...
This opening statement perfectly encapsulates the evolution of watch sizing preferences. What was once considered oversized in the 1950s is now considered a classic, almost dainty size by today's standards. The 39mm Explorer, introduced in 2010 (reference 214270), struck a balance, appealing to those who found the 36mm too small while still retaining a sense of understated elegance that defines the Explorer line. This sweet spot in size is a key factor in the enduring popularity of the 214270, encompassing both the Mk1 and Mk2 variations.
Rolex Explorer Review: A Deeper Dive into the 39mm Models
Both the Mk1 and Mk2 39mm Explorers share a core identity: robust construction, exceptional reliability, and a clean, functional design. However, subtle differences exist that appeal to different tastes and preferences. Let's examine these variations within the broader context of a Rolex Explorer review.
The Rolex Explorer Mk1 (214270 – Early Production):
The initial production run of the 214270, often referred to as the Mk1, is characterized by several features that have become highly sought after by collectors. These include:
* Slightly Thicker Case: Early examples often exhibit a slightly thicker case compared to later production Mk2 models. This difference is minute, barely noticeable to the naked eye, but significant to discerning collectors.
* Specific Dial Variations: Minor variations in dial printing, lume plots, and hand styles can be observed across early production models. These subtle differences contribute to the unique character of each individual watch. Some collectors specifically seek out watches with certain dial characteristics.
* Early Movement: The early Mk1 models housed the calibre 3131, a robust and reliable movement known for its accuracy and longevity.
The Rolex Explorer Mk2 (214270 – Later Production):
The Mk2 represents the later production run of the 214270. While the overall design remains consistent, some subtle changes were implemented:
* Slightly Thinner Case: As mentioned earlier, the case thickness was slightly reduced in later production. This is often attributed to manufacturing refinements and optimizations.
* Dial and Hand Consistency: Rolex standardized dial and hand production, resulting in greater uniformity across the Mk2 models. While this reduces the variability appreciated by some collectors, it ensures consistent quality and appearance.
* Movement Refinements: Though still the calibre 3131, subtle improvements and refinements within the movement likely occurred over time, potentially resulting in even greater accuracy and reliability.
