Watchmakers use jewel bearings to reduce friction and help the delicate parts of the movement work smoothly and with great precision. Jewels: Within a movement, metal on metal contact creates wear and tear. Ionic Plating: Process that produces a hardened surface that is durable and scratch-resistant Has a black flat "stealth" finish. Guilloche: Style of engraving that features wavy or straight lines, giving a unique effect when the timepiece is moved or shifted. In this regard, GMT is thought of as "the world's time" and was once the basis with which every other zone set time. Greenwich Mean Time is the average time that Earth takes to rotate from noon to noon. It is the place from where all time zones are measured. Greenwich Mean Time (GMT): Also referred to as Greenwich Meridian Time, the Greenwich Meridian Line is located at the Royal Observatory in Greenwich, England.
G CHRONO PLUS FIT MANUAL
COSC is a prestigious Swiss government agency that certifies the accuracy and precision of timepieces in Switzerland.Ĭrown: Part that allows you to manipulate the watch movement for a variety of purposes such as setting the hands, changing the date, winding the mainspring, etc.Ĭrystal: Transparent cover on a watch face that gives view of the dial.ĭeployant: Type of clasp that keeps the closing mechanism hidden, creating an uninterrupted look for your bracelet or strap.Įxhibition Case Back: Unique complication wherein a crystal window is implemented into the back of a watch case, allowing view of the timepiece's movement.įunction Pushers: Manual controls on a case for when a movement features complications that require increased manipulation. To become a chronometer, timepieces have to pass a test conducted by the Controle Officiel Suisse des Chronometers (COSC), roughly translating to Official Swiss Chronometer Testing Institute. The crown controls the analog watch while function pushers allow you to start, stop and reset the chronograph subdials.Ĭhronometer: High-precision timepiece that has been tested and is certified to meet precision standards Chronometer watches often come with certificates indicating their certified status.Ĭomplication: Any feature added to the timepiece that does not indicate hours, minutes or seconds.ĬOSC Certified Chronometer: Refers to timepieces that have been christened with the title of chronometer. Only tells time and I guess I am stuck with the watch face that it is on now.ATM: Measures water resistance Stands for "atmospheres" or the amount of pressure a watch can withstand before leaking One atmosphere is equal to 10 meters of water pressure.īezel: Retaining ring topping the case and securing the crystal Sometimes incorporates unidirectional or ratcheting movements, engraved or printed chapter markers, or complications such as a tachymeter.Ĭhronograph: Functioning similarly to a stopwatch, a chronograph is a unique and valued complication due to its ability to measure increments of elapsed time while the watch still maintains traditional timekeeping abilities. At least the watch used to work without the app but not any more. I hate to give up on this but after a year it is obvious the app developer has NO IDEA what he or she is doing.
The HR works and shows on the watch face but won’t record there.
G CHRONO PLUS FIT BLUETOOTH
How is this app still available? FIX IT!!!!!! Months later your app HAS CRASHED! It says my watch is paired with the app and Bluetooth says it’s connected but the app also says I have not added a devise. Makes a good watch and you can check blood pressure and heart rate and steps with watch but no way to record without the app. None of the functions work from the app since it won’t connect. The watch is fine but I have had mine for 5 months now and the app will not connect to the watch any more. set the range of the BP under user profile.
G CHRONO PLUS FIT UPDATE
I suspect the BP could be corrected with a software update that would allow the user to adjust the parameters, I.e. Overall, the tracker is a good deal with a good price and many great features.
Operating all of the features has a strong learning curve and I have not mastered everything yet. The phone pairing is a great feature and a real convenience. It is an attractive wrist tracker and very functional. The watch face is adjustable with several designs to choose from. The BPM is more accurate and the SPO is very accurate. It is totally un-reliable, giving a reading at least 12 points below my actual BP. The blood pressure monitor on this tracker is the most inaccurate of the trackers I own. I monitor my health and need accurate information. I am in generally good health but do have some problems from my adventurous life. I purchased this one for the health data reporting.
