The Real Reason Rolex Discontinued the “Pepsi” GMT-Master II (Ref. 16710): A Diagnosis, Checks, Solutions, and Prevention

**Title:** Diagnosing Rolex’s Discontinuation of the "Pepsi" GMT-Master II (Ref. 16710)
The discontinuation of the iconic Rolex "Pepsi" bezel GMT-Master II (Reference 16710) in 2007 was not a single event but a convergence of strategic, material, and market pressures. To understand the root cause, we must diagnose the likely factors in a safe, logical order.
### Section 1: Likely Causes (Diagnosis via Safe Order Checks)
**Check 1: The "Sandwich" Cerachrom Revolution (Strategic Priority)**
– **Cause:** In 2005, Rolex introduced the proprietary **Cerachrom** ceramic bezel (first on the Submariner). Ceramic offered near-perfect scratch resistance and color permanence versus the older anodized aluminum insert.
– **Why it forced the end:** The "Pepsi" (red/blue) two-tone ceramic insert was extremely difficult to manufacture consistently. Early attempts by Rolex (and later confirmed by industry leaks) produced an unacceptably high failure rate. The *blue* and *red* ceramic sections expanded and bonded poorly. Rolex prioritized Cerachrom across the GMT line. It was simpler to discontinue the aluminum "Pepsi" (red/blue) entirely than to offer a mixed line of old aluminum and new ceramic references. The "Coke" (red/black) and "Pepsi" (red/blue) were culled; the "Pepsi" was the most iconic and hardest to replace.
**Check 2: Production Costs & Supply Chain Complexity (Material Economics)**
– **Cause:** The anodized aluminum bezel inserts, while cheaper in raw material, required a multi-step dyeing and sealing process. Rolex was consolidating production to focus on the new, higher-margin Cerachrom process (which uses high-pressure sintering and diamond cutting). Maintaining a separate production line for a single aluminum bezel color combination (Pepsi) for a niche model was inefficient.
– **Verification:** Rolex discontinued the entire 16710 line (black, blue, and Pepsi) simultaneously, not just the Pepsi. This was a clean break, not a gradual death.
**Check 3: The Rise of the "Super Case" (Design Consistency)**
– **Cause:** In 2005-2007, Rolex was moving toward the chunky "Super Case" design language (thicker lugs, larger crown guards). The Ref. 16710 was a last-generation slim case (40mm). The new GMT-Master II (Ref. 116710LN in 2007) was a Super Case. The older Pepsi bezel did not visually fit the new, more masculine case architecture.
– **Rolex’s decision:** Rather than "frankenstein" a new ceramic Pepsi bezel onto an old case, they wait until 2018 to reissue the Pepsi (Ref. 126710BLRO) on the new Super Case with a fully successful ceramic bezel.
**Check 4: Market Dilution & Hype Management (Brand Control)**
– **Cause:** The aluminum Pepsi was widely available and sometimes sold below retail in the early 2000s. Rolex wanted to create a *scarcity* pecking order. Discontinuing the iconic color created immediate demand for the new black ceramic (Ref. 116710LN) and set the stage for future, blockbuster "re-editions" (like the 2018 Pepsi).
– **Result:** The discontinuation *was* the marketing event. It allowed Rolex to control the narrative of the "Holy Grail" GMT.
### Section 2: Solutions (Post-Facto & Strategic)
Since the discontinuation itself is a *fait accompli*, the "solutions" here apply to collectors, dealers, and Rolex’s post-2007 strategy.
**Solution 1: For Collectors – The "Pre-Ceramic" Market**
– **What to do:** Acquire a mint-condition Ref. 16710 "Pepsi" while it’s still affordable (prices have surged but not as high as ceramic models). Insist on a full set (box and papers) to verify authenticity.
– **Why it works:** The aluminum Pepsi is now a "neo-vintage" icon. It’s the only red/blue GMT that fits a slim, 40mm case.
**Solution 2: For Rolex – The 2018 "Ceramic Pepsi" Reissue**
– **What they did:** After 11 years, Rolex solved the ceramic manufacturing problem (using a patented "fused" process) and released the **Ref. 126710BLRO** on a Jubilee bracelet.
– **Why it was the solution:** It satisfied demand without devaluing the original; it created a new, equally desired (but different look) Pepsi.
**Solution 3: Aftermarket Humble Solutions (Not Rolex-Approved)**
– **For the cautious:** If you own a black bezel 16710, you can *buy* an aftermarket aluminum Pepsi insert and have a watchmaker install it. **Warning:** This voids factory integrity and will kill resale value to purists. Use only for personal wear.
### Section 3: Prevention (How to Avoid Future Discontinuation Pain)
**Prevention 1: Buy a Discontinued Watch Immediately (Window of Opportunity)**
– **Rule:** The moment a model is discontinued, buy a *new old stock* (NOS) example within 30 days. Prices are still at retail. After 6 months they double. The 16710 Pepsi could be had for under $5,000 in 2008. By 2010, they were $8,000.
**Prevention 2: Diversify in "Safe" Lines (Rolex’s Strategy)**
– **For brands:** Do not put all legacy production into one bezel. Rolex learned this by keeping the black bezel GMT in ceramic (116710LN) even while killing the Pepsi.
– **For buyers:** Own a "modern ceramic" and a "vintage aluminum" version of any iconic watch, so you are hedged against material changes.
**Prevention 3: Demand Transparency in Manufacturing (Unrealistic but Ideal)**
– **For Rolex:** Publicly state *why* a color is being retired (e.g., "Cerachrom red-blue not ready"). Rolex never did this, leading to speculation. In 2018, they finally admitted the technology challenge.
### Section 4: Escalation Conditions (When to Notify or Act)
**Escalation Condition 1: Price Bubble / Flipping Frenzy**
– **Trigger:** If a discontinued watch’s secondary market price exceeds 2x retail within 12 months.
– **Action (for collectors):** **Sell immediately** if you are not a long-term holder. The 16710 Pepsi spiked from $7k to $15k in 2018-2020. Smart money sold at $12k.
– **Action (for Rolex):** **Reissue** the model with a new material to crash the flipper market (which they did in 2018).
**Escalation Condition 2: Counterfeit Explosion**
– **Trigger:** High demand for a discontinued model (like the 16710 Pepsi) leads to fake bezels and repainted dials.
– **Action:** Rolex’s service centers should **refuse to service** any fake bezel. Buyers should demand **verification of lume (tritium vs. Luminova)** and **patent numbers** on the insert.
**Escalation Condition 3: Production Complication (Manufacturing Only)**
– **Trigger:** A new material (like Cerachrom) proves impossible to produce in two colors for >5 years.
– **Action:** **Abandon the color entirely** (as Rolex did) rather than release a flawed product. Then work in secret on a new alloy formula.
**Escalation Condition 4: Threat to Brand Equity (Context. Rolex)**
– **Trigger:** If the discontinued watch becomes *too* mythical (e.g., the "Kermit" Submariner), it undermines the current lineup.
– **Action:** **Reissue with a twist** (e.g., Cerachrom Pepsi on Jubilee) to reset the narrative and pull value back to the brand, not just the secondary market.
**Final Diagnosis:** Rolex’s discontinuation of the Pepsi GMT was a calculated, technology-driven move disguised as a strategy. The root cause was **Cerachrom failure** (material science) combined with a **marketing pivot** toward the "Super Case". The solution was patience—11 years to perfect the ceramic red-blue. The prevention for future collectors is to **buy the last aluminum version of any iconic watch before the ceramic replacement arrives**. Escalation should only occur if the secondary market begins to treat the watch like a stock, or if counterfeiters overrun the market.
