Few modern dive watches command the respect of the Rolex Deepsea 136660. Purpose-built for extreme underwater environments and engineered to withstand pressures far beyond human limits, the Deepsea stands as one of Rolex’s most technically sophisticated creations. For collectors who appreciate uncompromising capability paired with unmistakable Rolex design language, the 136660 defines the category.

Rubber B – recognized globally as the pioneer of Swiss-made vulcanized rubber straps precision-engineered for Rolex timepieces, continues to serve Deepsea owners who seek a strap worthy of the watch’s formidable architecture and mission-driven design.

This 2025 overview revisits the evolution of the Deepsea line, compares the previous generations, and highlights what makes the Rolex Deepsea 136660 the most refined version to date.

A Legacy of Depth: From the 116660 to the 126660 to Today’s 136660

Rolex rarely accelerates its development cycle. Yet the Deepsea has received three significant updates within a relatively short period: 2008, 2018, and 2022, demonstrating Rolex’s continued commitment to pushing engineering boundaries.

Below is a refined, collector-focused comparison.

Rolex Deepsea 116660 ,  The Original Engineering Statement (2008)

When released in 2008, the Rolex Deepsea 116660 redefined what a dive watch could achieve. Its purpose was clear: build a Rolex capable of surviving depths that approach the technical limits of modern mechanical watchmaking.

Key Highlights

• 44 mm case diameter, a significant departure from traditional Rolex proportions at the time.
  
• Caliber 3135 movement with a 48-hour power reserve.
  
• Ringlock System debut, a patented nitrogen-alloy compression ring paired with a helium escape valve, enabling the watch to withstand depths of 3,900 meters / 12,795 ft.
  
• A blueprint for modern Deepsea identity: oversized presence, extreme rating, maximum utility.

The 116660 introduced a new era, one defined not by cosmetic upgrades, but by aggressive technical ambition.

The 2018 update brought deep structural and mechanical enhancements, even though the aesthetic remained familiar.

Key Improvements

• Introduction of the Caliber 3235, featuring a Chronergy escapement, optimized efficiency, and an increased 70-hour power reserve.
  
• More than 90% new components, backed by 14 new patents.
  
• Subtle refinements to the bracelet and lugs to improve wearability.

For collectors, the 126660 marked a shift from raw capability to refined durability and precision.

The Rolex Deepsea 136660 represents the most evolved expression of the Deepsea philosophy. Rolex adjusted only what enhances functionality or visual harmony, staying true to its signature incremental evolution.

Notable Enhancements

• Slimmer bezel profile, emphasizing the sculpted lines of the chamfered sapphire crystal.
  
• A larger date window, expanded by approximately 8%, improving legibility without disrupting the dial’s balance.
  
• Optimized Chromalight display, engineered to deliver longer-lasting, more consistent blue luminescence.
  
• Removal of the Fliplock dive extension, an unexpected choice that has generated discussion among collectors. Rolex has not publicly disclosed the motivation for this adjustment.
  

The 136660 preserves the soul of the Deepsea while offering a cleaner, more contemporary presence, making it a compelling choice for 2025 Deepsea enthusiasts.
