HKM-685139 Twosome Automatic Moon Phase Tourbillon

Refined Engineering, Uncompromising Detail

Tourbillon: The Heart of Precision

The tourbillon carriage rotates continuously to average out positional errors caused by gravity. Mounted within a lightweight titanium cage, this mechanism delivers a captivating visual ballet while improving rate stability. The intricate finishing on the bridge and escapement reflects the dedication invested in this movement.

Moon Phase: A Celestial Companion

At a glance, observe the current phase of the moon with a dedicated sub-dial. The polished disc, decorated with stars and a golden moon, advances discreetly every 24 hours. Accurate to within one day every 122 years, this complication marries romanticism with mechanical rigor, providing a functional and poetic addition to the dial.

Titanium Case: Strength Without Weight

Crafted from Grade 5 titanium, the 41 mm (1.61 in) case offers exceptional corrosion resistance and a featherlight feel on the wrist. At just 11 mm (0.43 in) thick, it slips comfortably under a cuff. The subtle brushed and polished surfaces reflect light with refined sophistication, while the hypoallergenic properties of titanium make it suitable for sensitive skin.

Exhibition Caseback: A Window to the Movement

The transparent caseback, fitted with a hardened mineral crystal, offers an unobstructed view of the automatic winding rotor, blued screws, and perlage finishing. Observing the tourbillon in motion from the reverse side becomes a private pleasure each time you take the watch off.

Water Resistance & Daily Durability

Rated at 30 meters (98 feet), the watch withstands accidental splashes, rain, and brief immersion. The screw-down crown and gasketed case construction ensure reliable protection. While not designed for swimming or diving, it handles the rigors of daily life with quiet resilience.

Bracelet & Clasp: Secure Comfort

A robust stainless steel bracelet (Seiko-sourced) integrates seamlessly with the titanium case, offering durability and a classic aesthetic. The folding buckle clasp with safety lock ensures the watch stays firmly in place, while the micro-adjustment feature allows a tailored fit for wrists of various sizes.

Why the HKM-685139 Stands Apart

Tourbillon at Accessible Value: Traditional tourbillon timepieces often command a significant premium. This model integrates a beautifully finished tourbillon without compromising on quality, making haute horology attainable.
Lightweight Daily Wear: Titanium reduces wrist fatigue dramatically compared to stainless steel. You enjoy the presence of a 41 mm watch with the comfort of a much smaller piece.
Dual Complications in Harmony: The tourbillon and moon phase are arranged to balance the dial aesthetically, preventing clutter while offering rich visual interest from multiple angles.
Scratch-Resistant Crystal: The mirror film surface offers excellent clarity and guards against everyday scratches, maintaining the dial's legibility for years.

Frequently Asked Questions

How do I set the moon phase correctly?
Pull the crown to the second position and rotate clockwise to advance the moon disc. Align the full moon with the center of the display window, then consult a lunar calendar to set the current phase. The moon phase advances once every 24 hours; minor adjustments every few months keep it accurate.
Is the tourbillon visible during normal wear?
Yes. The dial cut-out at 6 o'clock frames the tourbillon carriage, allowing you to appreciate its rotation at a glance. The exhibition caseback further reveals the mechanism from behind.
Can I swim or shower with this watch?
The 30M (98 ft) water resistance rating is suitable for splashes, rain, and hand washing. It is not recommended for swimming, diving, or prolonged submersion. Avoid operating the crown when the watch is wet.
What type of movement does it use?
The watch houses an automatic mechanical movement produced in Taiwan, featuring 21 jewels and a frequency of 21,600 vibrations per hour. The self-winding mechanism builds power reserve through wrist motion, with a manual winding option available via the crown.
How should I care for the titanium case?
Titanium is highly resistant to corrosion but can develop surface scratches over time. Wipe the case with a soft microfiber cloth after wear. Avoid contact with abrasive surfaces. A gentle soap solution and soft brush can be used for occasional deeper cleaning.

Been buying these for years. They are relatively cheap and easy to replace, so much better than getting ripped off at the dealer lmao. Compatibility and Installation - 5/5 Filtration Efficiency and Performance - 5/5 Durability and Value for Money - 4/5 - these are made to be replaced, so can't really do much about that!

Perfect

I bought this and was able to change this myself. It was simple. I got this for my 2016 Honda Civic, I don't think I ever replaced the filter in my car in the 5 years that I had it. It had a distinct smell in my car, and once I popped this bad boy in, within a day or two the smell was gone. It did make a sound for a while like I did not do it correctly, but I did, after about a week the sound went away, so everything's good. I will buy this again when the time comes
