Roventa Incabloc, Ref. 3887, Women’s Manual Wind, 1976

A black Roman-numeral ring frames the warm beige center of this 1976 Roventa Incabloc, reference 3887. Dark, blued-style hands and a gold-tone pinion accent the two-hand display, surrounded by an oval gold-plated case. The women’s Swiss hand-wound watch is fitted with a new blue croco-style leather strap.

Roman chapter ring and oval case

Roventa appears on the beige center, with INCABLOC and SWISS MADE below. Gold-tone Roman numerals surround it on the black outer ring. There is no date window or running seconds; the two slim dark hands and gold-tone central pinion keep the center spare.

A rounded oval profile and polished bezel define the case of this vintage dress watch. It measures 29 mm across and 34 mm from lug to lug, with a 14 mm strap fit. Gold plating provides the warm exterior finish. An unsigned gold-tone fluted crown sits at 3 o’clock for winding and setting.

Caseback construction and new blue leather

The back carries Base Metal Bezel, Stainless Steel Back, Unbreakable Mainspring, Swiss Made and reference 3887. The bezel is base metal, while the back is stainless steel. Incabloc denotes the movement’s shock-protection system.

The new adjustable blue leather strap has a croco-style texture, matching blue stitching and a light underside. Its gold-tone buckle echoes the case, while the vivid leather contrasts with the black ring. The strap is a replacement accessory, separate from the original watch-head components.

The Swiss manual-wind movement powers the hour and minute display. The watch has been fully serviced and is fully operational. The watch-head components are original; the unsigned crown’s originality has not been separately established. Box and papers are not included. It comes with a 12-month warranty, with worldwide shipping from Vintage Watch Studio.
