Object description

Collaboration and Dial Construction

The Erwin-LAB03 represents a collaborative project combining Habring²'s manufacturing, Massena LAB's design direction, and dial work by American independent watchmaker J.N. Shapiro. The dial is constructed from bronze with hand-turned engine work, highlighted by a central basket-weave guilloché pattern reported to have been created using an 80-year-old straight-line guilloché machine.

Visually, this bronze-toned dial is framed by a circular brushed chapter ring marked with printed Roman numerals and an outer minute track. Time is indicated via blued steel hands, comprising open-tipped Breguet-style hands for the hours and minutes alongside a slender central seconds hand.

“Bronze hand-guilloche dial made signed by J.N. Shapiro”
“The central section of his bronze dial features a basket-weave pattern made on an 80-year-old straight-line guilloché machine.”
“Warm bronze-toned dial featuring a central basket-weave guilloché pattern and a circular brushed chapter ring with printed Roman numerals.”

Case Architecture and Reported Movement

The watch features a stainless steel case measuring 38.5 mm in diameter, characterized by brushed flanks, a prominent polished stepped bezel, and a fluted winding crown set at the 3 o'clock position. The case is fitted with an attached dark blue textured leather strap secured by a stainless steel pin buckle.

Internally, the timepiece is reported by the seller to run on the hand-wound calibre A11MS, plated in 5N rose gold. Derived from the Habring² Erwin line, this calibre incorporates a dead-beat seconds complication, where the central seconds hand advances strictly in discrete one-second intervals rather than a continuous sweep.

Evidence for this section

“Stainless steel with stepped bezel”
“Cal. A11MS, hand-winding, plated in 5N rose gold”
“A mechanical movement wherein the central seconds hand advances in one second increments across the dial”

Documentation and Production Limitations

This edition was constrained to a total production run of 66 pieces, dated circa 2022. The catalog listing redacts the individual edition sequence number as 'XX/66', although the accompanying documentation—comprising a warranty card, Habring² booklet, and a chronometer certificate from the Horological Society of New York—reportedly confirms the specific edition number.

Because the movement and reverse of the case are not depicted in the provided visual record, details concerning internal decoration, serial engravings, and overall internal condition rely entirely on the auction house descriptions and accompanying paper documentation.

Evidence for this section

“A limited edition of just 66 pieces”
“CASE NUMBER: XX/66”
“WITH: Warranty card, Habring²booklet confirming the limited edition number, chronometer certification from the Horological Society of New York”

Open research questions

What is the specific limited edition number obscured by the catalog entry's 'XX/66' notation on the case back and booklet?
What specific performance parameters or timing figures are recorded on this watch's Horological Society of New York chronometer certification?
