The Citizen Promaster Tough commonly nicknamed the “Ray Mears” is a 40 mm, light-powered field-style watch with a stated 300-metre water-resistance rating. The black-dial titanium-bracelet version is BN0118-55E; “Ray Mears” is an enthusiast nickname, not the designation on Citizen’s product page.
Its combination of a simple fixed-bezel design, Super Titanium, sapphire crystal and Eco-Drive makes it an unusual outdoor tool watch. Citizen describes its 300-metre rating as suitable for scuba diving, but the smooth fixed bezel does not provide the elapsed-time scale of a conventional dive watch.

What is the Citizen Promaster Tough Ray Mears?
Citizen’s Promaster line includes watches designed around practical functionality. The BN0118-55E is listed by Citizen UK as a Promaster Tough: a military-inspired, three-hand watch with a date, black dial, white hands and markers, and a silver-tone Super Titanium case and bracelet.
Ray Mears is an English bushcraft and survival educator and television personality. The nickname is associated with his earlier on-screen relationship with a Citizen Promaster Tough. The sources consulted do not establish the current watch as a formal Citizen–Ray Mears collection, and Citizen’s product page identifies it by the Promaster Tough name and reference number.

For the black-dial bracelet configuration, look for BN0118-55E. The related BN0118-12L has a blue dial and fabric strap; it is a different configuration. Use the reference rather than a seller’s “Ray Mears” label to identify the watch.
Citizen Promaster Tough BN0118-55E specifications
| Specification | BN0118-55E |
|---|---|
| Display | Analog three-hand display with date |
| Case size | 40 mm |
| Case and bracelet | Silver-tone Super Titanium |
| Crystal | Anti-reflective sapphire |
| Movement | Light-powered Eco-Drive |
| Water resistance | 300 metres; Citizen marks it as suitable for scuba diving |
| Other stated protections | Shock resistance, anti-magnetism, and resistance to temperatures from -10°C to +60°C |
These figures are manufacturer specifications from Citizen UK’s BN0118-55E product page. They describe the stated model features, not a guarantee that any used example retains its original condition or water resistance.
A field watch with 300 metres of water resistance
The defining characteristic is the contrast between the watch’s field-style appearance and its stated rating. The BN0118-55E has a clean dial, prominent markers and a smooth fixed bezel, while Citizen rates it to 300 metres.
That does not make it a conventional dive timer. A rotating bezel is commonly used to track elapsed immersion time, and this watch has no rotating timing scale. It is more accurate to describe it as a highly water-resistant field or tool watch that Citizen says is suitable for scuba diving, rather than a watch with a complete dive-timing bezel.

1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteFor outdoor use, the combination offers an analog field-watch presentation with substantial stated water resistance. As with any watch, condition and seal integrity matter, particularly on a pre-owned example.
Why Super Titanium matters
Citizen specifies Super Titanium for the case and bracelet. The material is a central part of the watch’s lightweight tool-watch design. Citizen also specifies anti-reflective sapphire crystal, which protects the dial and is intended to reduce reflections.
Neither material makes the watch indestructible. Hard impacts can damage a watch, and sapphire can chip despite its scratch resistance. Citizen’s stated shock, anti-magnetic and temperature protections are manufacturer specifications, not proof that every example will withstand unlimited abuse.
Eco-Drive: the low-maintenance advantage
The BN0118-55E uses Citizen Eco-Drive, which is powered by light. Citizen says the watch never needs a battery; in practical terms, Eco-Drive avoids routine battery replacement, not all maintenance. It offers a convenient alternative to a mechanical field watch for buyers who prioritize light-powered quartz timekeeping.

The watch review describes the BN0118 family’s case as monobloc or front-loading: service access is from the crystal side rather than through a conventional removable caseback. The review notes that some work can be more specialized than on a conventional screw-back watch, particularly when it involves the crystal, seals or pressure testing.
This construction does not mean the watch never needs service, and it is not a reason to attempt case opening with improvised tools. For servicing or water-resistance checks, use Citizen’s service network or a qualified watchmaker familiar with the design.
On the wrist: strengths of the design
Citizen lists a 40 mm case. Fit depends on wrist shape and the bracelet as well as case diameter; the available research does not establish exact thickness or lug-to-lug measurements for this reference, so those figures should not be inferred from a related variant.
The design follows a deliberately uncomplicated formula: three hands, clear markers and a date. The appeal is its practical analog presentation, titanium construction, stated water resistance and Eco-Drive operation, rather than a complicated set of functions.

If considering an aftermarket strap, verify compatibility with the specific watch and fit it carefully. A strap change does not maintain or increase water resistance; the case seals, not the strap, determine that. If a spring bar or lug is damaged, have it checked before wearing the watch.
Buying the watch in 2026
Availability and price vary by region and can change. Citizen UK’s BN0118-55E page showed a price of £399 and purchase controls when accessed on October 7, 2026. Treat that as a dated UK page observation, not a guarantee of current stock, price, or delivery in another country.
Listings may include new stock, pre-owned watches, or related references. Citizen’s product page identifies the exact black-dial titanium-bracelet model as BN0118-55E; do not assume a listing is that configuration just because it uses the “Ray Mears” nickname.
Reference-check checklist
- Confirm the reference: look for BN0118-55E if you want the black-dial titanium-bracelet version.
- Confirm the configuration: distinguish it from the blue-dial fabric-strap BN0118-12L and other Promaster Tough models.
- Check the seller and warranty: verify seller status and regional warranty terms, especially for an imported watch.
- Inspect condition: look for damage to the crystal, case, lugs and bracelet.
- Ask about service and water resistance: for a used watch, request service history and recent pressure-test evidence before relying on it in water.
- Confirm operation: if an Eco-Drive watch is stopped, it may need light exposure, but persistent problems warrant professional assessment.
Used-buying cautions
A water-resistance rating is not permanent. Seals age, and impacts or service can affect water resistance. For a pre-owned example, recent pressure-test evidence is more meaningful than a seller’s assurance that the watch “looks waterproof.”
Do not immerse an older or previously opened example until its water resistance has been checked. If the seller cannot establish when it was tested or serviced, allow for professional inspection before relying on it in water.
Who should buy the Citizen Promaster Tough Ray Mears?
It makes sense for buyers who want:
- a simple analog outdoor watch rather than a digital instrument;
- a titanium case and bracelet;
- light-powered quartz operation that avoids routine battery replacement;
- sapphire crystal;
- substantial stated water resistance; and
- a restrained field-watch design.
Look elsewhere if you need:
- a rotating bezel for dive-time measurement;
- a watch whose used water resistance you can rely on without testing;
- a specific case dimension not confirmed in the available specifications; or
- a formally designated Ray Mears edition.
Do not buy solely because a listing uses “Ray Mears” as a premium-generating label. The nickname explains the watch’s enthusiast association, but evaluate the exact reference, configuration, condition, seller and warranty.
Verdict
The Citizen Promaster Tough BN0118-55E is best understood as a field-style analog watch with a stated 300-metre water-resistance rating. Its Super Titanium case and bracelet, sapphire crystal and Eco-Drive movement make it a practical option for buyers who want a simple, light-powered outdoor watch.

FAQ
Is the Citizen Promaster Tough Ray Mears an official Ray Mears watch?
“Ray Mears” is an enthusiast and watch-publication nickname associated with Mears’s earlier on-screen relationship with a Citizen Promaster Tough. The sources consulted do not establish the current BN0118-55E as a formal Citizen–Ray Mears collection.
What is the reference number for the Citizen Ray Mears watch?
The black-dial, titanium-bracelet model is BN0118-55E. The related BN0118-12L has a blue dial and fabric strap, so check the reference and configuration when shopping.
Is the Citizen Promaster Tough Ray Mears a dive watch?
Citizen marks the BN0118-55E’s 300-metre rating as suitable for scuba diving. Its smooth fixed bezel has no elapsed-time scale, so it does not offer the conventional dive-timing function of a rotating bezel.
How water-resistant is the Citizen Promaster Tough BN0118-55E?
Citizen specifies 300 metres of water resistance and marks the watch as suitable for scuba diving. Seals can age and condition can vary, so have a used example pressure-tested before relying on it in water.
Is the Citizen Promaster Tough Ray Mears easy to service?
The review describes the case as front-loading or monobloc, with access from the crystal side rather than a conventional removable caseback. It notes that some service work can be more specialized; use a qualified watchmaker or Citizen service network.
