Delivery & Returns
Q: What is the Cartier Santos Octagon 25mm Ref. 187903? A: It’s a vintage two‑tone Santos featuring a 25mm stainless steel case with an 18k yellow‑gold octagonal bezel, a cream dial with black Roman numerals and a date at 3 o’clock, a reliable Swiss quartz movement, a crown set with a blue sapphire cabochon, and a stainless steel bracelet accented by 18k yellow‑gold screws.
Q: Is this watch quartz and does it need a battery? A: Yes. The watch is powered by a Swiss quartz movement that requires a battery. Typical battery life is around 2–3 years; we recommend professional replacement so the gaskets can be checked and the case properly resealed.
Q: Is it water‑resistant? A: As with any vintage watch, water resistance cannot be guaranteed without a recent pressure test. Please treat it as splash‑resistant only and avoid swimming, showering, or full submersion unless a watchmaker has tested and confirmed its seals.
Q: Will this watch fit my wrist? A: This specific piece is sized to fit a wrist of up to 17 cm. The bracelet can be shortened by removing links. Additional links are not included with this listing; if you require a larger size, compatible links may be sourced separately by a watch specialist.
Q: Can I swap the bracelet for a leather strap? A: The Santos Octagon uses an integrated bracelet design. Converting to a strap typically requires model‑specific end links and the help of a skilled watchmaker. It is not a simple quick‑release swap.
Q: What is the condition of this particular watch? A: It is graded Very Good overall with light traces of use. There are surface scratches on the case, case back and bracelet consistent with age and careful wear; please review the photos for a close look.
Q: What exactly is two‑tone on this model? A: The case and bracelet are primarily stainless steel, while the octagonal bezel is crafted from 18k yellow gold and the bracelet features 18k yellow‑gold screws. This combination delivers Cartier’s signature steel‑and‑gold aesthetic.
Q: How do I set the time and date? A: Gently pull the crown to the first click to set the date, and to the second click to set the time. After adjustment, press the crown back in firmly. To protect the mechanism, avoid changing the date between about 9 pm and 3 am.
Q: Is this size considered women’s or unisex? A: Historically, 25mm Santos Octagon models were marketed to women, but today many collectors of all genders appreciate the elegant, compact proportions of vintage Cartier designs.
Q: What is included and is there a warranty? A: This listing is for the watch only (no original box or papers). A Retro Tale guarantees 100% authenticity and provides a 12‑month movement warranty covering the watch’s functional performance, along with secure, insured delivery and a 14‑day return policy.
