12. What is a perpetual calendar?
A perpetual calendar is a watch complication that automatically adjusts for different month lengths and leap years.
13. What is a tachymeter?
A tachymeter is a scale on the bezel or dial used to measure speed based on time and distance.
14. What is an exhibition case back?
This is a transparent case back, usually made of sapphire or mineral glass, allowing you to see the watch movement.
15. What is a crown?
The crown is a knob on the side of the watch used to set the time and wind the movement on mechanical watches.
16. What is a bezel?
A bezel is the ring surrounding the watch face. On dive watches, it’s typically unidirectional and used to track elapsed time.
17. What is a case back?
This is the rear cover of the watch. It can be solid, transparent, or screw-down depending on the watch type and water resistance.
18. What is power reserve?
Power reserve is the amount of time a fully wound watch will continue to run before it stops.
19. What is a rotor?
In automatic watches, a rotor is a weighted piece that moves with wrist motion to wind the mainspring.
20. What is hacking seconds?
Hacking is a feature that stops the second hand when the crown is pulled out, allowing for precise time setting.
21. What is a balance wheel?
This is a component in mechanical watches that regulates timekeeping through oscillation.
22. What is a watch movement?
The movement is the mechanism that drives the watch hands and powers complications. Types include quartz, mechanical, and automatic.
23. What is the lug width?
This is the distance between the lugs of a watch and determines the strap width that fits the watch.
24. What is a field watch?
A field watch is a military-inspired, rugged timepiece designed for durability and legibility.
25. What is a pilot watch?
Pilot watches have large dials, bold numerals, and often include chronograph or GMT features to assist pilots.
26. What is a racing watch?
These watches typically feature chronograph functions and tachymeter scales to track lap times and speeds.
27. What is a moonphase complication?
This displays the current phase of the moon, usually in a small aperture on the dial.
28. What is a minute repeater?
A high-end complication that chimes the time on demand using a series of gongs and hammers inside the case.
29. What is anti-magnetic protection?
Watches with anti-magnetic protection resist timekeeping interference caused by exposure to magnetic fields.
30. What is a COSC-certified chronometer?
A COSC-certified watch has passed rigorous tests for accuracy and is certified by the Swiss Official Chronometer Testing Institute.
31. What is a tonneau case?
A tonneau-shaped case resembles a barrel and offers a unique, elegant aesthetic.
32. What is a skeleton watch?
A skeleton watch exposes parts of the movement, either through the dial or case back, to show the internal mechanics.
33. What is an integrated bracelet?
An integrated bracelet is designed to flow seamlessly into the watch case for a cohesive look.
34. What is an annual calendar?
An annual calendar adjusts for month lengths but requires manual adjustment once per year, typically in February.
35. What is a jumping hour?
A digital-style complication where the hour hand jumps to the next numeral rather than gradually sweeping.
36. What is a regulator watch?
A regulator separates the hour, minute, and second hands onto different dials for enhanced precision reading.
37. What is a flyback chronograph?
A flyback allows the chronograph hand to be reset and restarted with a single press of a button.
38. What is a dual time watch?
Similar to a GMT, it allows tracking of two time zones, typically using separate hour hands.
39. What is a pulsometer?
A pulsometer is a scale used to measure heart rate based on counting beats over time.
40. What is a Breguet hand?
A stylized watch hand with a looped tip, often seen in classical and luxury watches.
41. What is a pin buckle?
A traditional strap closure mechanism similar to a belt buckle, offering adjustability and ease of use.
42. What is a deployant clasp?
A deployant clasp folds open and closed, allowing the watch to be put on or taken off without fully unbuckling the strap.
43. What is a NATO strap?
A durable fabric strap that loops under the watch and through both lugs, known for its security and military heritage.
44. What is a bracelet?
A bracelet is a metal strap, usually made of stainless steel, titanium, or precious metal links.
