The Rolex Explorer II Ref. 16570

The Rolex Explorer II Ref. 16570 stands as a testament to Rolex's commitment to functional elegance and durability. Produced from 1989 to 2011, this model has become a favorite among watch enthusiasts for its versatility and understated charm. Let's delve into the details that make the Explorer II 16570 a sought-after timepiece.

Design Features

The 16570 maintained the classic 40mm case size, striking an ideal balance between presence and wearability. It was offered in two dial variants: black and white (often referred to as "Polar"). The white dial version, in particular, gained popularity for its striking contrast and excellent legibility.

One of the most distinctive features of the Explorer II is its fixed 24-hour bezel. Unlike the rotating bezels found on models like the GMT-Master II, the Explorer II's fixed bezel serves as a constant reference for the watch's 24-hour hand. This feature was particularly useful for professionals working in environments

where distinguishing between day and night could be challenging, such as cave explorers or polar researchers.

Beyond the Dial notes that the Explorer II transitioned from being marketed as a spelunker's watch to a more versatile timepiece for expeditions across different time zones. This shift in positioning helped broaden its appeal beyond niche professional use.

Movement and Functionality

The Explorer II 16570 was initially equipped with the Rolex Caliber 3185 movement. This automatic movement featured a jumping hour hand, allowing for easy adjustment when changing time zones. Later models (around 2005-2006) received an upgrade to the Caliber 3186, which introduced the Parachrom hairspring for improved shock and temperature resistance.

The GMT functionality, with its distinctive red 24-hour hand, allows wearers to track a second time zone. This feature, combined with the watch's robust construction, made it an ideal companion for travelers and professionals working across different time zones.

Bracelet and Wearability

The 16570 came fitted with Rolex's Oyster bracelet. Early models featured hollow end links, while later versions were upgraded to solid end links (SEL). Fratello Watches points out that the introduction of solid end links significantly changed the feel of the watch, making it feel more modern and substantial on the wrist.For those looking to customize their Explorer II, aftermarket options are available. Steel Reef, for instance, offers an 'On the Fly' extension link that allows for easy micro-adjustments, enhancing the comfort and wearability of the watch.

Collecting and Value

The Explorer II 16570 has seen a surge in popularity among collectors in recent years. Its relatively accessible price point (compared to other Rolex sports models) and versatile design make it an attractive option for both new and seasoned collectors.

When considering a 16570 for purchase, there are several factors to keep in mind:

1. Dial Variant: Both black and white dial versions are popular, with the Polar dial often commanding a slight premium.

2. Lume Type: Earlier models feature tritium lume, identifiable by the "SWISS-T<25" marking at the bottom of the dial. Later models transitioned to Luminova and then Super-Luminova.

3. Case Holes: Early versions featured drilled lugs, while later models had no-holes cases. This can help in dating the watch.

4. Bracelet Type: Check for the correct bracelet and end link combination for the production year.

5. Movement: Determine whether it's the earlier 3185 or the later 3186 caliber.

Maintenance and Care

Like all Rolex watches, the Explorer II 16570 is built to last. However, proper care and maintenance are essential to ensure its longevity and performance. Regular servicing by a qualified watchmaker is recommended every 5-10 years, depending on usage.

For those interested in customizing their Explorer II, aftermarket parts are available. Ewatchparts, for example, offers compatible bracelet links for the 16570. However, it's important to note that using non-Rolex parts may affect the watch's value and warranty.

Wrapping It Up

The Rolex Explorer II Ref. 16570 represents a sweet spot in Rolex's sports watch lineup. Its combination of robust functionality, classic design, and relative value has made it a favorite among enthusiasts and collectors alike. Whether you're drawn to its adventure-ready heritage, its GMT functionality, or simply its understated elegance, the Explorer II 16570 offers a compelling package that continues to stand the test of time.

As with any vintage or pre-owned watch, thorough research and authentication are crucial before making a purchase. The Explorer II 16570's long production run and various subtle changes over the years make it an interesting study for collectors, with each era offering its own unique charm and collectibility.
