CHRONOGRAPH ALARM

A watch that has both stopwatch and alarm functions

COMPASS DIRECTIONAL RING

A rotating ring that can be used to determine your direction by using the position of the sun and the time of day

COUNTDOWN TIMER

Function that tells how much of a preset period of time has elapsed

CROWN

The “knob” used to set the time and/or the date

CRYSTAL

The clear lens that covers the “face” of the watch; it is often made of plastic, glass or mineral glass (a harder glass composite that is resistant to scratching and breaking)

DEPLOYMENT BUCKLE

A three part folding closure mechanism

DIAL

The “face” of the watch

DIGITAL

The screen showing time and other functions in numerical digits

DIVER’S WATCH

A watch that is water resistant to 200 meters; it should have a one way rotating bezel and a screw down crown and case back

DUAL TIME

Measures current local time as well as another time zone; additional time zone is displayed by a twin dial, extra hand or sub-dial

DUST RESISTANT

A watch that is engineered and assembled to minimize dust particle penetration; this is crucial to it’s efficient functioning; to maintain dust resistance, do not leave the crown disengaged from the case for extended periods of time

ELAPSED TIME RING

If your watch is equipped with a rotatable outer dial with numbers and indicators, this Elapsed Time Ring may be used to indicate the length of time remaining for an activity or the starting time of an activity.

TIME REMAINING- set the outer ring so that the triangle is pointing to the time the activity is to end.

STARTING TIME - set the triangle on the time the activity is to begin.

GMT (Greenwich Mean Time)

(Also known as Zulu time) is set to the international clock in Greenwich, England and is used by pilots worldwide; 2nd time zone may read from a hand making a full rotation in a 24 hour ring indicating AM or PM

HYPOALERGENIC

Although Nautica watches have stainless steel case backs and bracelets, they are not hypoallergenic.

INTERNATIONAL / MILITARY TIME

Hours numbered to 24 (01:00 to 24:00). As seen on digital read-outs or sub-dials.

IP (ION PLATING)

A process that fuses the color into the metal resulting in superior bonding and producing a hard, durable finish 

LUMINOUS

When a self-illuminating material is used on watch hands or markers causing them to glow in the dark

MICRON

Measurement (one millionth of a meter) used to gauge the thickness of metal plating

MILITARY / 24 HOUR TIME

When time is measured in 24 hours segments; usually shown on sub-dials

MINI-SWEEP

A sub-dial that measures seconds

MOON WATCH (AM/PM)

Rotating moon display showing the sun (AM) and the moon (PM)

MOTHER OF PEARL

Iridescent milky interior of oyster shells that is sliced thin and used on watch dials

MOVEMENT

The inner mechanism of a watch that enables it to measure time; a quartz movement measures the vibrations in a piece of quartz, is highly accurate and is powered by a battery

MULTI-FUNCTION

Any watch with functions in addition to normal time
- 3-Eye multi-function: Analog + (day + date + 24 hour/military time eyes at 3-6-9).

RATCHET BEZEL

A rotating ring around the dial to measure periods of elapsed time up to 60 minutes

RESIN

A synthetic material used in watch straps that is lightweight, durable and pliable

RETROGRADE

A movement utilizing a pointer hand on a sub-dial which moves in an arc and springs back when it’s cycle is completed

ROSE GOLD

When a small amount of copper is added to the metal alloy creating a pink gold color

SCREW DOWN CROWN

A crown which screws close to the case and ensures superior water resistance

SHOCK RESISTANCE

As defined by the Federal Trade Commission regulation, a watch’s ability to withstand an impact equal to that of being dropped onto a wood surface from a height of 3 feet

SLIDE RULE

A rotating bezel that is printed with a logarithmic scale that can be used to do mathematical calculations or navigational computations

SPLASH RESISTANT

Basic water resistant construction; cannot be reliable and is not suitable for showering or swimming

SQUARE

Any style with a square or rectangular case

STAINLESS STEEL

An extremely durable metal alloy that is virtually immune to rust, discoloration and corrosion; since it does not contain nickel, it is hypoallergenic

STEM

The shaft that connects the crown to the movement

SWAROVSKI®

Austrian manufacturer of quality faceted crystals

TACHYMETER

Feature used to measure a rate of speed over a fixed distance in miles per hour (MPH), nautical miles per hour (KNOTS) or kilometers per hour (KPH); the sweep second hand and the scale reflector ring or bezel are used

TITANIUM

A silvery-gray metal that is much stronger but much lighter than stainless steel, hypoallergenic, able to withstand extreme temperatures and resistant to salt water corrosion

WATERPROOF

The Federal Trade Commission forbids the use of this term as it relates to watches since no watch is truly 100% waterproof

WATER RESISTANT

Describes the level of protection a watch has from water damage; watches will withstand water pressure up to their respective ratings as long as the crystal, crown, case, push buttons and gaskets remain intact

WATER RESISTANT LEATHER STRAPS

Surface leather, interior padding and lining are specially treated to be water resistant and to maintain shape, size and color fastness after drying.
