Quartz wrist watch bearing text reading "FREDERIQUE CONSTANT"

This is a white-dial quartz wrist watch featuring a complex calendar and moon phase complication. The watch is constructed with a polished stainless steel round case and a matching linked metal bracelet. The white dial features a subtle geometric guilloche pattern in the center, large black Roman numeral hour markers, and blued steel hands for the hours, minutes, and subsidiary dials. A red-tipped pointer hand tracks the outer perimeter scale corresponding to months and week numbers, ranging from January through December. There are two primary subsidiary sub-dials: the left sub-dial indicates the days of the week (MON through SUN), while the right sub-dial indicates the date using a 1-to-31 numerical track. A moon phase aperture is positioned at the 6 o'clock position, displaying a golden moon and stars against a dark blue background. Text on the dial includes "FREDERIQUE CONSTANT" beneath the 12 o'clock position and "SWISS MADE" at the very bottom edge flanking the 6 o'clock marker. The owner supplies the context that this is a "FREDERIQUE CONSTANT FC-270X3P4 Moon Phase Chronograph Quartz Watch", but please note that user-supplied claims and visible dial text are unverified by physical inspection, and the item's authenticity remains unevaluated. Condition issues visible in the photograph include minor surface scratches and wear on the polished bezel and crystal edge near the 3 o'clock position. The style is consistent with late 20th-century or contemporary Swiss dress watches featuring multiple calendar complications. Hedged language is used in the item name because visible text and markings alone do not constitute proof of authenticity without expert in-person verification.

Based on what I can see in the provided photograph, this is a white-dial quartz wrist watch featuring a complete calendar and moon phase complication, housed in a polished stainless steel case with a linked metal bracelet. The dial bears text reading 'FREDERIQUE CONSTANT' and 'SWISS MADE'. Per user submission, the owner identifies this as a 'FREDERIQUE CONSTANT FC-270X3P4 Moon Phase Chronograph Quartz Watch'. I cannot verify the authenticity, internal movement quality, or exact materials from a photograph alone; physical inspection is required to confirm whether these markings correspond to a genuine piece. Assuming the attribution is correct, contemporary quartz dress watches with multiple complications from comparable Swiss makers typically trade in the $400 to $700 range on the secondary market, depending on condition. The item exhibits minor surface scratches and wear on the polished bezel and crystal edge near the 3 o'clock position, which slightly detracts from its value. If the item were to turn out to be a reproduction, replica, copy, or produced 'in the style of' rather than an authentic piece bearing that name, the value would decrease significantly, likely dropping to the $50-$150 range as a generic fashion watch. To confirm authenticity and establish a precise market value, an in-person examination by a qualified horologist, movement inspection, and review of any accompanying provenance documentation or original packaging would be necessary.
