Both the case, bracelet, and clasp are treated with a special HV1200 surface coating, giving the entire watch excellent scratch resistance. With a hardness close to 1200 Vickers, it holds up impressively well to daily wear and tear.
Paired with 20 ATM water resistance, Super-LumiNova BL 10 X1 for reliable low-light visibility, TIDSLINJE is designed to perform, and look good doing it – in any setting.
9122 Automatic movement
Every element has been refined to create a harmonious interplay between brushed and polished surfaces. This meticulous attention to detail is evident in the chamfered edges on the bracelet, bezel, and lugs.
The box-shaped sapphire crystal adds depth and creates subtle edge distortions – a retro-inspired detail that adds character. The raised box profile allows more space for the hands, helping keep the case height to a minimum despite the advanced complication.
The crown’s color-matched insert and tone-matched date display seamlessly complement the watch’s cohesive design.
TIDSLINJE is powered by an automatic movement, the Premium-Series Miyota 9122 movement.
The movement has a power reserve of 42 hours, and is a high-beat movement with a beat-rate of 28.800 BPH
The Premium Series 9122 is a high-end, Japanese automatic movement manufactured by Miyota (a subsidiary of Citizen).
In the watch world, it is part of Miyota’s „9-Series“ (specifically the 91XX family), which was designed to compete directly with Swiss-made movements like the ETA 2824-2. It is highly regarded by microbrands because it offers „luxury“ specs—like a high beat rate and complex complications—at a much more accessible price point.
Key Technical Specifications
The 9122 is often called a „Triple Calendar“ movement because of the specific information it displays:
- Complications: Central hours, minutes, and sweeping seconds, plus:
- Day of the week sub-dial (usually at 9 o’clock).
- Month sub-dial (usually at 3 o’clock).
- Date window (usually at 6 o’clock).
- Beat Rate: $28,800$ vibrations per hour (vph) or $4$ Hz. This results in a very smooth, „sweeping“ motion of the second hand compared to cheaper movements.
- Power Reserve: Approximately 40 hours.
- Jewels: 26 jewels (used to reduce friction in the gear train).
- Accuracy: Factory-rated at $-10$ to $+30$ seconds per day (though many microbrands regulate them to be much tighter).
- Winding: Both automatic (self-winding via a rotor) and manual hand-winding.
- Hacking: Yes (the second hand stops when you pull out the crown, allowing for precise time setting).
Why is it „Premium“?
- High-Beat Smoothness: Most affordable automatics (like the Seiko NH35) run at $21,600$ vph. The 9122’s higher frequency makes the watch feel and look higher-end.
- Slim Profile: Despite having multiple calendar gears, it maintains a relatively thin height ($5.52$ mm), allowing watch brands to design sleek, elegant cases rather than bulky ones.
- Reliability: It is known as a „workhorse“ movement. It’s robust, rarely fails, and is easily serviceable by almost any local watchmaker.
One Small Quirk to Note
The Miyota 9-series uses a unidirectional winding rotor. This means the rotor only winds the spring when it spins in one direction. When it spins the other way, it „freewheels“ very quickly. You might occasionally hear or feel a slight „zip“ or vibration on your wrist—collectors often call this the „Miyota Shuffle,“ and it’s a signature characteristic of this premium movement!
