The Rolex Submariner Date 41 mm (reference 126618LB) embodies the legendary diver’s watch in its most luxurious form. Crafted entirely from 18 k yellow gold, it features a royal blue dial and matching Cerachrom bezel insert in blue ceramic. Combining the durability of Rolex’s professional dive heritage with the elegance of precious metal, the 126618LB is both a technical instrument and a statement of timeless refinement.

Introduced in 1953, the Rolex Submariner redefined the professional dive watch. The current 41 mm Submariner Date 126618LB continues that legacy in full 18 k yellow gold, featuring a radiant royal-blue dial and matching Cerachrom bezel. Built to perform at depths of 300 meters / 1,000 feet, it combines Rolex’s pioneering underwater engineering with unmistakable luxury. The Submariner remains a symbol of precision, endurance, and elegance — a timepiece equally at home beneath the surface or in the most refined settings.

Gamzo & Co. is a trusted secondary-market luxury-watch dealer based in Los Angeles. We specialize in sourcing authentic, unworn and pre-owned Rolex and other fine timepieces, offering insured nationwide shipping, transparent service, and personalized attention — without waitlists or uncertainty.

WATCHES

General Information

Who is Gamzo & Co., and where is it based?

Gamzo & Co. is a luxury timepiece retailer specializing in high-end Swiss watches from brands such as Rolex, Audemars Piguet, Patek Philippe, and more. We are based in Los Angeles, California, in the heart of the Diamond District, and serve clients nationwide and internationally.

What makes Gamzo & Co. different from other companies?

We focus on delivering wholesale pricing, transparency, and personal service. Every watch we sell is carefully vetted for authenticity and condition, and we work one-on-one with clients to source specific models when needed. No guesswork — just expert guidance and trusted sourcing.

Is Gamzo & Co. an authorized dealer for the watch brands it sells?

Gamzo & Co. is not an authorized dealer. We operate in the secondary market, which allows us to offer hard-to-find, discontinued, and highly sought-after models. It also means our customers skip the waitlist, and get watches delivered right to their doors! All watches are guaranteed authentic and come with original box and papers when specified.

Most watches include the original box and warranty papers, unless otherwise stated in the product description. If a watch does not include these items, it will be clearly disclosed prior to purchase.

How can I verify the authenticity of a watch I purchase from you?

You may verify authenticity by:

  Inspecting the original warranty card and serial numbers;
  
  
  
• 
  Having the watch reviewed by a Rolex or authorized brand service center; or

  Consulting an independent third-party watch expert.

Where do you source your luxury watches from?

Our watches are sourced from a trusted global network of authorized retailers, collectors, dealers, and private clients. Every piece undergoes strict verification before entering our inventory.

Warranty

Are your new watches covered by warranty?

Yes. New watches typically include the manufacturer’s international warranty, valid from the date on the original warranty card.  All of our watches are also covered by our Gamzo & Co. one-year limited warranty.  Please see the Gamzo & Co. limited warranty page for additional information. 

What does your warranty cover, and how long does it last?

How do you evaluate and price a watch I want to sell or trade in?

Pricing is based on:

• 
  Brand, model, and reference;
  
  
  
• 
  Condition and completeness (box & papers); and
  
  
  
• 
  Current market demand and pricing trends
  
  
  

We aim to offer fair, competitive market value.

Can I trade in my current watch towards a purchase?

Yes. Trade-ins are welcome and can be applied toward watches from brands such as Rolex, Audemars Piguet, or Patek Philippe, subject to availability and evaluation.  Please contact us for a trade evaluation.

How long does the appraisal process take?

Most appraisals are completed within 24–48 hours once we receive all required details or the physical watch.

Exchanges and Returns

What is your return or exchange policy?

Due to the nature of luxury timepieces, all sales are final unless otherwise stated. Exceptions may be made at our discretion if a watch is materially misrepresented.

Are there any restocking fees on returns or exchanges?

If a return or exchange is approved, a restocking fee may apply depending on the circumstances and condition of the watch.
