ROLEX GMT Master II Watch

Q: What is the Rolex GMT‑Master II ref. 116710BLNR (“Batman”)?
A: It’s a 40mm stainless‑steel Rolex travel watch featuring a black and blue ceramic GMT bezel, automatic movement with independent 24‑hour hand, date display with Cyclops magnifier, Oyster case and steel Oyster bracelet with a folding clasp. It’s designed to track multiple time zones with precision and durability.

Q: Which movement does it use and what is the power reserve?
A: Many 116710BLNR models house the Rolex automatic Calibre 3186 with GMT and date functions. Expect a power reserve of approximately 48 hours. If you’d like us to confirm the exact calibre in this specific piece, just ask.

Q: How do I set local time, home time and the date on a GMT‑Master II?
A: Unscrew the crown. Position 1: wind the watch (20–30 turns if stopped). Position 2: adjust the local hour hand in one‑hour jumps; the date changes with the local hour hand—avoid setting the date between roughly 8pm and 2am. Position 3: set the time by moving the main hands; align the 24‑hour GMT hand to your home time. To track a third time zone, rotate the bezel to the desired offset and read against the GMT hand. When finished, push the crown in and screw it down firmly.

Q: Is it water‑resistant and suitable for swimming?
A: The Oyster case was originally rated to 100 metres, but water resistance on pre‑owned watches is not guaranteed without recent servicing and pressure testing. We recommend avoiding swimming or showering unless seals have been replaced and the watch has been tested by an authorised watchmaker. Always ensure the crown is fully screwed down before any exposure to moisture.

Q: What is special about the black/blue ceramic bezel and will the colours fade?
A: The ceramic insert is highly scratch‑resistant and its colour is integral to the material, so it should not fade under normal use. Like all ceramics, it can chip or crack if subjected to hard impacts. The bezel is bi‑directional and works with the GMT hand to read a second or third time zone.

Q: Does it have a sapphire crystal and Cyclops date magnifier?
A: Yes—this reference features a scratch‑resistant sapphire crystal with Rolex’s Cyclops magnifier over the date for enhanced legibility.

Q: Will the 40mm case suit my wrist, and can the bracelet be resized?
A: The 40mm case offers a versatile, modern profile suitable for many wrists and is commonly worn unisex. This example’s bracelet is sized to approximately 17 cm and can be adjusted. It is delivered with two additional link pieces; extra links can often be sourced if needed—share your wrist measurement and we’ll advise.

Q: Is it battery‑powered and how accurate is it?
A: It’s an automatic self‑winding mechanical watch—no battery required. Performance typically aligns with Rolex’s Superlative Chronometer standards (around −2/+2 seconds per day under ideal conditions), though actual accuracy depends on age and service history.

Q: How often should it be serviced and how should I care for it?
A: A routine service every 5–10 years is generally advised, or sooner if you notice timekeeping or water‑resistance issues. Keep the watch away from strong magnets, rinse with fresh water after salt exposure (once water‑resistance is verified), and clean with a soft microfiber cloth. Have seals checked periodically if you plan to be near water.

Q: Is the 116710BLNR still in production, and how does it compare to newer models?
A: The 116710BLNR has been discontinued and succeeded by the 126710BLNR, which features Rolex’s newer movement generation. The 116710BLNR remains highly sought‑after for its original “Batman” black/blue aesthetic and classic proportions.

Q: What is included with this watch and how do you guarantee authenticity?
A: As stated in the listing, this piece is delivered with original box, booklet, warranty card, hangtags and two link pieces. A Retro Tale professionally authenticates every item and provides a 12‑month mechanical guarantee for peace of mind. We can share further details or photos on request.
