We've noticed something interesting about our customers. Many start their watch journey fascinated by basic timekeeping. The clean sweep of hands, the satisfying tick of automatic watches. Then curiosity grows. Those extra dials on certain models catch your eye. The additional hands are tracking something beyond local time. The mysterious window showing lunar phases. Suddenly, you're ready to explore deeper. Let's walk through what makes these features work and why we believe they matter.

What We Mean by Complications
In watchmaking, we call any function beyond basic time display a "complication." The name fits—these features genuinely complicate the movement's design. We're adding components that must work flawlessly alongside the timekeeping mechanism.
Consider what goes into a chronograph. We integrate roughly 50 to 100 additional parts into the base movement. Each wheel, lever, and spring must mesh perfectly with existing components. Tolerances matter tremendously here—we're talking measurements finer than a human hair's width.
Our approach comes from German engineering traditions. We don't chase feature counts. We'd rather perfect two complications that you'll actually use than cram in five that mostly gather dust. This philosophy shapes every movement we develop.
The finishing work becomes crucial with added complexity. More components mean more friction points, more surfaces needing lubrication, and more potential for timing errors. We polish every pivot hole, chamfer each gear tooth edge, and test each complication independently before assembly.
We always ask ourselves: Will someone genuinely use this? Our Lausanne Tourbillon includes GMT functionality because we know our customers travel internationally. Every complication we include answers a real need.
How We Build GMT Functionality
Our GMT watches track two time zones simultaneously. We named this feature after Greenwich Mean Time, the reference point that organized global navigation and aviation. Pilots originally needed these watches during the jet age—now business travelers and remote workers find them indispensable.
We use what's called a "true GMT" movement architecture. Pull the crown to the first position, and you can jump the local hour hand forward or backward without stopping the watch. The GMT hand keeps tracking your home time zone continuously. This matters when you're landing in Singapore at 3 AM and need to reset your watch without calculations.
Watch how the GMT hand moves on our pieces. It rotates smoothly around the 24-hour scale—no jumping, no hesitation. Poor execution shows immediately in this detail. The hand should align precisely with hour markers throughout its rotation.
In our Lausanne Tourbillon, we've integrated GMT functionality into a movement running at 28,800 vibrations per hour. The tourbillon mechanism counters gravitational effects on accuracy while the GMT complication tracks your second time zone. We test each movement extensively to verify the GMT hand maintains accuracy across all 24 hours.
Look closely at our 24-hour scales. We use deep printing that won't fade over the years of wear. The GMT hand contrasts clearly against the dial—instant readability matters when you're checking time zones quickly.
Engineering Chronograph Precision
Adding stopwatch functionality to a mechanical watch requires intricate engineering. Press the pusher, and a coupling mechanism engages the chronograph wheels with the constantly running movement. Press again to stop. The reset pusher uses a heart-shaped cam to snap hands back to zero.
We consider chronographs among watchmaking's most demanding complications. We use column wheel mechanisms—toothed pillars controlling all chronograph functions through vertical operation. Some manufacturers use cam-lever systems instead. Both work well when executed properly. We chose column wheels for their crisp, positive action.
Feel the pushers on our Tirona Chronograph. They click decisively with no mushiness, no travel before engagement. The reset should snap hands to zero precisely, not drift close to position. These tactile qualities tell you everything about the internal adjustment quality.
We calibrated the stopwatch pushers for daily timing needs—tracking your workout intervals, timing your cooking, and measuring elapsed project time. We added date functionality because most people want that information accessible. The 5 ATM water resistance means you're not babying this watch during normal activities.
Examine our chronograph subdials. We finish them with polished accents that catch light differently from the main dial. The center chronograph seconds hand aligns exactly with dial markers when running—no approximations.

Moon Phase Mechanics
Moon phase displays track lunar cycles through a rotating disc showing moon positions against a background aperture. A 59-tooth gear drives this disc, advancing one tooth every 24 hours. This creates the 29.5-day lunar cycle mathematically (59 teeth divided by 2).
Traditional moon phase complications require manual correction once every couple of years as the mechanism drifts from the actual 29.53059-day lunar month. High-precision versions use 135-tooth gears for accuracy spanning over a century. These refined mechanisms show watchmaking's pursuit of astronomical precision.
Moon disc artistry should be taken seriously. Quality execution requires hand-painting or multi-layer printing with dimensional shading. Stars in the background should appear crisp. The aperture's shape frames the moon properly—poor execution cuts off moon phases awkwardly during transitions.
The moon phase mechanism should be positioned carefully. Mounting them dial-side requires secure attachment, preventing slippage over the years. Better implementations drive the moon disc from the movement side through long stems, isolating the display from external pressure or crystal impacts.
Our Manufacturing Heritage
As a family-owned operation, we maintain quality through direct oversight. Each watchmaker knows their work carries our family name forward. This accountability shows in detail what others might overlook—how complicated hands center, how smoothly pushers operate, how accurately complex functions track over months of wear.
We run extensive laboratory testing before any watch leaves our facility. Complications undergo position testing in multiple orientations. We temperature cycle them to verify lubrication remains stable. Long-duration timing tests confirm sustained accuracy. Our movements spend days in these evaluations before we even consider case assembly.
We select materials deliberately. Specialized alloys resist corrosion and magnetism better than standard brass. For complications containing many additional wheels, material choices significantly impact performance over decades.
Our finishing philosophy serves function first. We employ Glashütte ribbing, polished bevels, and blued screws—but always ask whether each element aids structural reinforcement, improves lubrication retention, or simplifies serviceability.
This means our complications work reliably for decades, not just years. Those additional 100-plus components in a chronograph movement need identical longevity to the base caliber. We refuse to cut corners on complication-specific parts.
How Complications Interact Within Movements
Complications don't exist in isolation—they interact within the movement's ecosystem. A chronograph consumes mainspring power even when not activated, as its wheels remain engaged with the gear train. GMT functions require additional wheel trains to split torque from the center wheel.
We face architectural choices in every design. Modular complications stack on base movements, simplifying manufacturing but adding thickness. Integrated complications weave into the original movement design, achieving flatter profiles but complicating service. We've used both approaches depending on the specific complication and intended use.
Our movements typically operate at 28,800 vibrations per hour—a frequency balancing accuracy with power consumption. Higher beat rates improve chronograph precision since each tick represents a smaller time increment. However, faster oscillation consumes more energy.
At Tufina, we test complications comprehensively. Basic timing machines verify accuracy over days. We evaluate complications through hundreds of activation cycles, temperature extremes, and sustained operation. Our laboratory protocols simulate years of wear, identifying weak points before watches reach your wrist.

How To Choose Complications That Match Your Life
Start honestly. Will you cross time zones regularly enough to justify GMT complexity? Do you actually time things daily, or would a chronograph mostly sit unused? Moon phases appeal more to aesthetic appreciation than practical necessity—and that's perfectly valid if it matters to you.
When evaluating any complicated watch, request to see the movement through the case back. Quality complications show consistent finishing across all components, not just the visible rotor. Check how the complication wheels mesh with the base movement. Sloppy integration reveals aftermarket additions rather than purpose-built calibers we engineer from the beginning.
Consider case dimensions. Chronographs typically add 2-3mm thickness versus time-only watches. GMT functions integrate more efficiently. Moon phases fit relatively flat since they're dial-side complications. Try the watch on—complications shouldn't make the piece uncomfortable for your wrist size.
Water resistance should match your activities. Chronograph pushers create potential water ingress points. We achieve 5 ATM on our Tirona Chronograph through careful gasket engineering while maintaining responsive pushers. Know your needs—desk work requires less protection than outdoor activities.
Test legibility in various lighting. Our GMT hands contrast clearly against the dials. Chronograph subdials are sized for quick reading. Moon phase apertures should obviously display current phases. Poor legibility defeats any complication's purpose regardless of mechanical excellence.
Think about service requirements. Complications mean more components requiring periodic maintenance. We design for serviceability—modular construction allowing complication removal without complete movement disassembly. Expect service roughly every 4-5 years. Our 2-year warranty provides assurance, and properly maintained pieces operate reliably far longer.
Questions We Hear Regularly
What's the difference between a chronograph and a chronometer?
This confuses many people despite describing completely different concepts. A chronograph provides stopwatch functionality. A chronometer represents a precision certification awarded after movement testing. Watches can be both, either, or neither.
Will complications affect accuracy?
Quality complications shouldn't degrade timekeeping if properly executed. Additional components create more friction and require more mainspring energy, which theoretically could affect timing. We account for this through proper gearing ratios and lubrication. We test movements extensively with all complications operating to verify sustained precision.
How often will I need service?
Expect service every 4-5 years with complications, slightly more frequently than with simple movements. Additional components need fresh lubrication, and parts like chronograph pushers require seal replacement. We focus on extending service intervals through superior materials and generous lubrication reservoirs.
Can complications be added later?
Generally no. Complications require purpose-built movements with space allocated for additional components from the initial design. Some modules can be added, but aftermarket additions rarely match integrated designs. This makes choosing the right complications initially important.
Are more complications better?
Not necessarily. Each complication adds mechanical complexity, maintenance requirements, and potential failure points. We focus on perfecting fewer functions rather than chasing complication counts. An excellent chronograph you use daily outperforms five complications you ignore.
