Med syftet att undersöka hur ett föremåls autenticitet påverkas av renovering/restaurering, har tolkningar av tre författares respektive syn på begreppet autenticitet applicerats på två restaurerade armbandsur. Renoverings- och restaureringsmetoden som har granskats är lasersvetsning, vilken är snabbt växande till följd av sina positiva egenskaper. Då armbandsurens ekonomiska värde stiger i takt med att det allmänna intresset blir större, finns relevans i att studera den renoverings- eller restaureringsmetod oftast diskuteras i samband med ekonomiskt värde. Även om författarnas ståndpunkter skiljer sig åt, så tycks en gemensam synpunkt vara att begreppet autenticitet är högst subjektivt. I förlängningen har det lett till slutsatsen att begreppet autenticitet ofta är individuellt och att det möjligtvis bör undvikas vid diskussion av konservering, restaurering och renovering. / With the aim to investigate how an object's authenticity is affected by the renovation/restoration, the interpretations of three authors respective views on the concept of authenticity is applied to two restored wristwatches. The renovation or restoration method that has been examined is laser welding, which is rapidly growing as a result of its positive qualities. Since wristwatches economic value rises in line with the public interest becomes greater, the study of the renovation or restoration method that is usually discussed in the context of economic value is relevant. Although the authors positions may differ, there seems to be a common denominator to the concept of authenticity as highly subjective. This has led to the conclusion that the concept of authenticity is often too individual and that it possibly should be avoided when discussing issues of preservation, restoration and renovation.

The following study examines watchmakers and the watchmaking school in Sweden, how these changed during the 20th century. This is done through Geert Hofstede´s theory about levels of analyzes, his different steps to reach culture history. The source material of the study is based on public investigations, scientific articles, newspaper articles, literature and interviews. The purpose of this study is to reach and understand what and why changes occur in the world of watchmaking, and if the watchmaker managed to survive these changes during the 20th century. Results from the study confirm that very little has changed in the watchmaking school, they still use the same methods as they did 300 years ago. The watchmakers in Sweden showed that they had the durability and flexibility to survive several changes, even if the world was in motion during most of the 20th century.
