  2. 2. At the end of this chapter, you will be able to:Understand about concept of fixingUnderstand about types of appliquésUnderstand about drawingObjectives2Functional Training
  3. 3. 3The Conceptof Fixing3Functional Training
  4. 4. Watches have now become lifestyleaccessories rather than a device that is usedto tell time. Since the dial is the face of thewatch it is undergoing continuous changeand innovation to meet these requirementsInitial changes were done in surface color,then surface finish, then dial shapes andnow it is done over appliqués. As appliquésare becoming more complex andcustomized, fixing becomes one of themajor processes to enhance the look andappeal of the dialBackgroundDial with indexDial with eddi4Functional Training
  5. 5. Initially the hour marks were printed on thedial and were represented by Arabic orroman numerals or mix of bothAfter that these became indexes which arefixed on the dialInitially the indexes were also Arabic orroman numerals or mix of bothSimple printed dialTwo piece dial withindexesChanging trends of Appliqués5Functional Training
  6. 6. Today these shapes could be anythingdepending upon the designs. With change inshape has come change in positioningbecause of chronographs, windows andother complex designsUnique shaped dialChanging trends of Appliqués6Functional Training
  7. 7. Fixing is a process in which appliqués aremanually fixed on the dial face one at a timeTweezers are used to pick up the appliquéand insert the appliqué feet on thedesignated holes on dial faceFixingDefinition of Fixing7Functional Training
  8. 8. Fixing is a critical process because the dial is now in its semi-final stage andthere is no scope for rework any more. A mistake means that the dial has to bemade again and this has an impact on the following:-Delivery compliance against plan will decrease because some dials have to beremadeStage wise quality rejection will increase leading to a greater risk of clientrejection.For dispatching the same quantity now more dials have to be produced andthis will reduce our productivity ratiosThe rejected dials are a waste and so this impacts our profitabilityLastly, since the dials are in the last stage and each rejected dial has a fargreater value as compared to dials in the first stage. At the prices of 2011, itwas calculated that while a blank costs Rs. 5/-, the dial in fixing stage is worthRs. 40/-. After finishing this cost now touches Rs 150/-Criticality of Fixing8Functional Training

  12. 12. EddiEddi is a sticker which is pasted on the dialsurfaceCustomized appliquésCustomized appliqués refer to some specialdesigns on the watch dial associated withcertain brands ex. rotorEddiRotorTypes of Appliqués12Functional Training
  13. 13. Customized appliquésCustomized appliqués also refer to sometrademark on the watch dial associated withcertain brandsBushingsBushing is an assembly of stone and holderwhere the stone is mounted on jaws given inthe holder. These bushings are used as timeindicators and their assembly as well asfixing is done in house at TTPATrademark and logoBushingTypes of Appliqués13Functional Training
  14. 14. PartsExcept for indexes, other appliqués appliedon the dial are called parts. For exampleouter rings, chrono rings logos, trademarksetcDial ringChronograph ringTypes of Appliqués14Functional Training
  15. 15. 15DrawingReading15Functional Training
  16. 16. Drawings are the ultimate reference pointfor any index or dial. At TTPA we havestandard formats for drawings and customerspecifications and requests are convertedinto these drawings. After the conversionthese drawings are used as the onlyreference point in the plant for all functionsincluding quality and production.DrawingReading the drawing16Functional Training
  17. 17. An index drawing specifies about the following dimensions of an indexShape : Shape of an index is the appearance of the index in form of Arabicnumerals, roman numerals, stick , pins and othersPosition : Position of the index is the position of that index on the specifiedhour markLength of indexWidth of indexIndex height : Height of index is normally referred as thickness of indexPitch of index feet : distance between the two index feet of a single index iscalled pitchFeet dia : diameter of the index feetFeet length : length of the feet of the indexFacet : Facet is the cut done over the indexColor of the index in terms of the plating doneIndex drawing17Functional Training

  23. 23. Position of the indexesThe dial drawing visually showcases the type of indexes to be fit on the dial andalso the position of the indexes on the dial. Index column shows visually thetype of indexes required and the dimension (length, width and height) andposition of the index. Index plating provides the details of the color of theindex.23Functional Training

  29. 29. Position of the indexesPitch is the distance between two points. All the holes drilled on the dial arehaving tolerances in microns and the pitch serves as the reference frame forthe position of the all these holes throughout the dial surface. Commonly usedexamples of pitch in dial manufacturing are as follows:-Distance between the center hole and index holeDistance between the two holes for fitment of indexDistance between two feet of the indexDistance between the center hole and outer hole of the chrono ringDistance between dial center hole and chrono ring center hole29Functional Training
  30. 30. Index drawing codes detailsAP stands for appliquésThe first two numbersdenote the length of theindex ex. – 325 means3.25 mmThese two lettersindicates the type offacet cut on the indexThe next letters denotethe type of indexEx. SI- Special indexThe next 2 numbersindicate the width of theindex ex. 11 means 1.10mmThis information is vital as it informsabout the position of the index on thedial ex. AT 8 Hr means the index hasto be placed at 8 hour markAPSI/3251/GC/AT 8 Hr(KDDL/ APSI/3300)- This code is a drawing number and one can use this reference toaccess this drawing from our database30Functional Training
