Catalogue description
Description — Lusto – Suomen Metsämuseo
Vanerista sorvattu pyöreä ja litteähkö seinäkello. Kellon keskellä on matala, suorapohjainen alue, josta hieman paksummat reunat kohoavat pyöreästi. Reunojen sivu on muotoiltu niin, että se laskee loivanpyöreästi kohti suoraa ja kapeaa ulkosivua. Takasivun puolella reunassa on hyvin loiva pyöristys, josta sivu jatkuu suorana. Takasivun keskelle on tehty pyöreä aukko, johon on painettu mustasta muovista tehty nelikulmainen kellokoneisto. Koneiston alapuolella on takasivuun upotettu pyöreä vanerinpala, jossa on polttopainettu merkintä MH. Kellon ohuesta metallista tehdyt viisarit ovat suorat ja mustat. Kellon pinta on hyvin sileä, etusivu on käsitelty läpikuultavan valkoiseksi, takasivu on pinnaltaan käsittelemätön.

Historical context
Contemporary Horology (2010 – Present)
Silicon components, connected watches, optical-lattice research clocks and a thriving independent scene.
Today time is distributed by satellite navigation and networks with nanosecond accuracy, while mechanical clocks are made as art, design and craft objects. Contemporary designers explore the clock as sculpture and kinetic art.

Atlas type guide
Regulators, wall and Vienna clocks
A regulator is a precision pendulum clock used as a time standard in observatories, workshops and railway offices. Typical features are a deadbeat or Graham escapement, a temperature-compensated pendulum (mercury jar, gridiron or later invar), maintaining power and a regulator dial that separates hours, minutes and seconds. George Graham's deadbeat escapement (c. 1715) and his mercury pendulum, together with Harrison's gridiron, set the pattern for two centuries.
Wall clocks span a much wider range: the elegant Viennese Laterndluhr and Dachluhr of the Biedermeier period, the Dutch stoelklok and staartklok, English 'dial' clocks used in schools, offices and railway stations, and mass-produced spring and weight wall clocks from Germany (Gustav Becker, Junghans, Kienzle) and America.
What to look for
- Deadbeat escapement and compensated pendulum (gridiron rods, mercury jar or wood rod).
- A regulator dial with a large central minute hand and separate hour and seconds dials.
- Vienna regulators: glazed cases, slender pendulum, small weights, enamel two-piece dials.
- German factory trademarks stamped on the backplate (e.g. Gustav Becker anchor and crown, Junghans star).
Dating clues
- Graham-type deadbeat regulators: from c. 1720.
- Viennese Laterndluhr: c. 1800–1850.
- German factory 'Vienna-style' regulators: c. 1870–1930; Gustav Becker serial numbers allow close dating.
