Heuer Titanium: the 1983 collection and LWO 283 chronograph
· Mamontrevintage
History of the Heuer Titanium collection: 1983 catalogue, titanium and gold, automatic LWO 283, ETA 2892 and Dubois-Dépraz chronograph module.

Heuer: from Saint-Imier to precision chronographs
Edouard Heuer founded a watch workshop in Saint-Imier in 1860, then moved it to Biel/Bienne in 1867. His 1887 patent improved the oscillating pinion used to engage and disengage a chronograph. The company continued developing timing instruments and mechanical sports chronographs.
Heuer expanded its professional dive-watch range from 1978 onwards. Its 1983 and 1984 catalogues contained the 1000, 2000 and 3000 Series, alongside Autavia and Carrera chronographs and the new Titanium models.
The 1982–1985 transition
Heuer's ownership changed in the early 1980s. Lemania was among the companies in the group that acquired the manufacturer in 1982. The Titanium collection debuted in 1983. Following acquisition by Techniques d'Avant Garde in 1985, the brand adopted the TAG Heuer name.
Titanium dials were produced with both Heuer-only and TAG Heuer signatures. The watch presented by Mamontrevintage has the Heuer-only logo from this historical production family.

Three watch families within Titanium
TAG Heuer's historical documentation describes three designs: fixed bezels with gold-coloured details; fixed bezels with black carbon-fibre details; and rotating bezels with gold-coloured details. Three-hand watches and chronographs appeared in multiple sizes.
The chronographs have subsidiary counters, a date at three and a tachymeter scale. The collection employed titanium cases and bracelets, with sapphire crystals and decorative inserts depending on the reference.
Titanium and the 1984 watch catalogue
The Heuer Time for Action catalogue from 1984 presents Titanium alongside aerospace imagery, including the space shuttle Columbia. The spacecraft first flew on 12 April 1981. This advertising reference reflects the period marketing of titanium as an advanced material.
The archival image reproduced here shows watches from the Heuer / TAG Heuer Titanium collection. The original period documents are preserved in TAG Heuer’s official historical archive.

LWO 283: an automatic modular movement
The LWO 283 consists of an automatic ETA 2892 base with a Dubois-Dépraz chronograph module. The manufacturer's official historical study links the development of the movement for Heuer to Lemania.
The ETA base provides timekeeping and automatic winding; the additional chronograph module measures elapsed time. This modular assembly differs mechanically from a chronograph movement designed as one integrated architecture.

Distinguishing the quartz Calibre 185
The Heuer Calibre 185 used an ESA 555.232 quartz base and a Dubois-Dépraz mechanical chronograph module. The LWO 283 uses a mechanical automatic ETA 2892 instead. They are two distinct movement architectures within a single design collection.
TAG Heuer's archive also documents modular chronographs in the 3000 Series. The technical identifiers LWO 283 and Calibre 185 specify the actual type of movement rather than the external dial layout.
The 1984 price list and the 1985 edition
According to a Heuer 1984 price list cited by TAG Heuer, three-hand Titanium watches cost about US$1,045–1,245 and quartz chronographs about US$1,525–1,800 depending on configuration. These are historical catalogue prices.
An Emerson Fittipaldi-themed limited Titanium chronograph appeared in 1985. TAG Heuer identifies that version as quartz-powered. The Heuer Titanium sold by Mamontrevintage is an automatic LWO 283 model.

The Mamontrevintage Heuer Titanium
This chronograph has a 38 mm case, a mechanical automatic LWO 283, titanium construction with 14-carat gold components, a signed buckle and its box. Its dial carries the original Heuer-only signature.
